FOREWORD

For the past five years the Heat Transfer and Physical Properties Section
of ORNL has investigated some of the physical properties of fluoride mixtures
of specific interest to the ANP Project. Particular attention has been given
to the "thermal properties”, namely, the density, heat capacity, viscosity,
and thermal conductivity, because of the important role that they play in the
heat and momentum transfer processes in ANP reactors. A limited study of the
electrical conductivity and surface tension of molten fluorides was also
conducted.

During the first few years of this research task, & large part of the group
effort was directed toward the investigation and evaluation of techniques and
devices by which these properties could be measured accurately in the temperature
range of about 1000°F to 1800°F. The necessity of operating equipment at such
high temperature levels as well as in controlled inert atmospheres often made
it impossible to use prosaic property equipment. Consequently many new devices
had to be developed.

The earlier summaries of the physical properties measurements for fluorides
were presented in the form of ORNL memoranda; some of these data were designated
as "preliminary" because measuring techniques were still in the process of being
refined and because the chemical purities of fluoride samples were at times
inadequate. The experimental data suwmarized in this report in most cases were
obtained by two independent measurement technigques; also, it is believed that
most of the samples used were relatively pure. Although much progress has been
made in the art and science of making these difficult measurements, further
refinements should be and are being made, particularly in the case of thermal

couductivity measurements for liquids.

M ke |
-vi-

 

General interpretations and correlations of these physical property data
in terms of the known theoretical and semi-theoretical relations have been and
are being made for the fluoride measurements. Such studies have already been
reported in some of the topical reports on individual properties (see for
example, ORNL 1702 and 1956). Additional topical reports on thermsl properties
are in the process of preparation.

In general, the molten fluorides &are good heat transfer media because
their thermel conductivities, thermal capacities per unit volume, and densities are
high and their viscosities and vapour pressures are reasonable; the following
tabulation gives the approximate ranges over which each of the thermal
properties varies:

thermal conductivity: 0.5 to 2.6 Btu/nr-ft°-(°F/ft)

thermal capacity per unit volume: 0.7 to 1.3 cal/cms-oc

density: 2 to 4.5 gm/cc

viscosity: 2 to 12 centipoise
These thermal properties influence the heat and momentum transfer in reactor
cores and heat exchangers in more or less complicated ways depending upon the
system geometry and the fluid flow regime. Hence, it is not possible to rate a
heat transfer fluid on the basis of its properties alone. However, detailed
studies of the effectiveness of molten fluorides as reactor coolants and fuels
(for a range of system geometries and flow conditions) have been conducted and
presented in the ANP literature (see for example references 48 and 49).

Within the last year or two, several externsl organizetions have initiated
thermal property research on flucride mixtures. The National Bureau of Standerds

and the Naval Resesarch Laboratory have made heat capacity measurements and the

research on these liquids.

The Heat Transfer and Physical Properties Section wishes to acknowledge
the cooperation received from two of the Laboratory's Divieions. The former
Materials Chemistry Division prepared the meny samples which were needed in
the study; valuable information on melting temperatures, vapor pressures,
and phase diagrams of molten fluoride mixtures were also supplied. The
Metallurgy Division performed complicated welding tasks in connection with

some of the physical property devices.

SUMMARY

This report presents a summary of certain physical properties that have been
determined experimentally on the fluoride mixtures that have been formulated
within the ANP program &t ORNL (Refs. 1, 2). These properties include the
density, enthalpy, heat capacity, heat of fusion, thermal conductivity,
viscosity, Prandtl number, electrical conductivity and surface temsion. In
addition to the experimental data, values'have been predicted for the heat
capacity and density of the other mixtures from the correlations of these
properties. ZEstimates of the viscosity have also been made for a number of the

mixtures on which no experimental data were available.

INTRODUCTION

This report presents a compilation of certain physical properties that
have been determined experimentally or predicted from correlations of experimental
data for mixtures of fluorides that have been formulated within the ANP program
(Ref. 1, 2) Each individual page of the tabulation is devoted to & summary of
all of the known properties for a mixture together with the composition in mole
and weight percent, the average molecular fieight; and the liquidus temperature.

This introductory section will present brief discussions of each of the
pr0per£ies, providing short descriptions of the experimental systems used and
statements regarding the accuracy of the data. Also included In this section

is a tabulation of the mixture numbers arranged according to chemical system.
A. Density.

Density measurements have been made on sixteen molten fluoride mixtures.
In addition, about nine mixtures containing BeF2 have been studied at Mound
Laboratoryl. Measurements were made by the buoyancy principle using & plummet
suspended in the molten salt from an analytical balance. An error analysis

indicated that the values reported are within +5% of the true values. The

results are reported in gms/cc as a function of °C and in lbs/ft3 as a function of °F.

 

;A large number of fluoride mixtures other than those reported here have been
studied at Mound Iaboratory. However, the contents of this report will be limited
to mixtures which have been assigned composition numbers within the ANP project at
this Laboratory.

Work at Mound is being carried out by B. C. Blanke, aided at present by
E. N. Bousquet and E. L. Murphy and in the past by L. V. Jones, K. W. Foster
and R. E. Vallee. The density (and viscosity) program there at present involves
a thorough investigation of systems containing the alkall fluorides with BeF2 and
UF) »
h
gy -3- o

Predicted values are given for all the mixtures for which densities have
not been experimentally studied. The values given for non-BeF2 mixtures are
based on an empirical correlation using the experimental data available (Ref. 16).
The densities of mixtures containing BeF2 have been predicted from a similarly
developed but slightly different correlation using the experimental data taken
on BeFe-bearing mixtures at Mound Laboratory. These relationships correlate
the experimental values to within +5% and it is felt that the predicted values
are of comparable accuracy.

So0lid densities at room temperature have been measured for fifteen mixtures.
The measurements were made by the buoyancy principle; samples of salt were weighed
in air and then in toluene. An error analysies indicated errors of no more than
+5%. Solid densities were calculated for the remainder of the mixtures by &
simple formula involving the method of mixtures (Ref. 16). These calculated
values agreed within +10% with the experimental values available in most cases;
however, a larger deviation was observed in one case which may be attributed to
structural complexities. -

Values of the volumetric coefficient of liquid expansion, BL, were calculated

from the experimental or predicted density data using the equation:

5 =-l(2.e
L p \d7T P
vhere (%%) is the slope of the density-temperature function. Values have been
P

calculated at 700°C except when specified otherwise.
B. Heat Capacity.

The enthalpies, heats of fusion and heat capacities of twenty-one salt mixtures

have been determined experimentally by dropping samples at various temperatures into

“’ i g
calorimeters and then measuring the amount of heat liberated.. The heat capacity
is the slope of the enthalpy-temperature relation thus obtained. Two types of
calorimeters have been used. One was an ice calorimeter in which the heat
given up by the sample melted ice in an ice-water mixture. The amount of ice
melted was proportional to the amount of heat transferred and was determined by
the volume change in the ice-water mixture. The other calorimeter was a copper
block device. The amount of heat liberated by the sample was measured by the
temperature rise of a large mass of copper. From the experimental values
obtained for the particular fluorides studied, correlations have been found
which enable one to predict the heat capacities of other mixtures (Ref. L).
Hence, estimetes have been made of the heat capacities of all the mixtures
not studied experimentally. The accuracies of the heat capacities determined
experimentally are believed to be within +10% of the true values; the predicted
values are believed to be in error by no more than +20%.

The heats of fusion for the fluo:ide mixtures were obtained directly from

the enthalpy-temperature relations.

Co Thermal Conductivity.

 

Thermal conductivities of seven mixtures in the liquid state have been measured
by variable gap devices (Ref. 11). The conductivity is determined by measuring the
temperature gradient across a liquid layer as well as the heat flow through it.

The layer thickness is varied so that it is possible to eliminate the effect of

interface resistances that may exist in the cell. The thermal conductivities of
several liquids were determined in & constant gap device. Great difficulty was

encountered when using this device because it was difficult to fill the cell

completely with the sample liquid. Two methods have been used to measure solid

:&i’:'.‘ :; .'“: # ".F-’ ) “
- -5 S

thermal conductivities; one is a steady state technique in which heat is passed
through a slab of the solid salt, and the other is a transient method in which the
time-temperature behavior of a solid sphere of the salt 1s studied.

Error analyses of liquid thermal conductivity measurements indicated that
the errors were less than +25%. It 1s believed that the solid thermal
conductivities are known more accurately than the liquid values. Consequently,
liquid conductivities in particular are considered to be of a preliminary nature
at this time. Improved conductivity devices are being designed to increase the
accuracy. The temperature dependence of the conductivities of fluoride mixtures
is currently being studied; the results indicate that the variation 1s not a

large one. Thus, only mean conductivities are reported here.
D, Viscosity.

Viscosity measurements have been made on thirty-eight molten fluoride
mixtures. Thirty-tfib of these were studied at ORNL and nine at Mound Iabnratoryg,

3 Measurements at ORNL were made

three being investigated at both laboratories.
with two devices; one of these is a capillary efflux viscometer and the other is a
modified Brookfield rotational device. Measurements were made at Mound with a
rotational viscometer developed there.

The values are presented in c.g.s. units and in engineering unite. Kinematic

viscosities are given as well as absolute viscosities. In addition, the viscosity

of each salt is presented in terms of the usual exponential formula for viscosity:

 

2A number of measurements have been made at Mound which are not reported here
{see footnote 1, page 4).

3The results obtained independently at the two laboratories were in satisfactory
agreement; the average values are reported here.
‘ b= ~

Agreement between the values determined by the two different instruments indicated
that the results reported are within +10% of the true values.

Predicted viscosities are given for & number of salts on which no measurements
wvere made. These estimates were based on measurements on fluorides of similar
compositions. These predicted values are probably within i?O% of the actual values.

A blank sheet of graph paper specially prepared for plotting viscosity
data is furnished at the end of this report to facilitate interpolation and

extrapolation of the values reported.

 

E. Electrical Conductivity.

The data on electrical conductivity included in this report were primarily
obtained by means of a current-potential type cell (Ref. 13)}. This device
measured directly the amount of current flow for a given voltage drop across a
molten salt sample. Measurements were made on five molten fluoride mixtures.
37 KEO3, and NaOH
were made within +10% of the values reported in the literature, it was felt

Since redeterminations of the conductivities of molten LiNO

that the fluoride messurements were in error by no more than this amount.

F. Surface Tension.

 

Surface tension measurements were made on one fluoride mixture, Composition
30, using a system consisting of a platinum ring supported from & calibrated
wire spring which could be raised and lowered with a vernier (Ref. 21). A
thermocouple probe was used to measure the surface temperature of the molten

fluoride as accurately as possible.

CONCLUDING REMARKS

The summary of physical properties presented in this report has been compiled
for the various technical groups within the AEP‘Project vho need it. Properties
have been measured or predicted for a large portion of the fluoride systems thet
have been of interest to the Project thus far. Tt is anticipated that more
measurements will be made for new fluoride systems as they become attractive.

In the meantime, however, in most cases the thermal properties of such new
fluoride systems can be estimated satisfactorily for preliminary design purposes
with the aid of the correlation relations that have been developed. For example;
molten densities have been related uniquely to room temperature densities or
molecular weight which can be calculated {see topicel report, ORNL 1702).

The heat capacities were found to be inversely proportional fio the average
molecular weight and directly proportional to the average number of atoms in
the mixture {see topical report, ORNL 1956). |

Topical reports on the viscosity and thermal conductivity research on
fluorides are being prepared. Viscosities have been found to vary with
molecular weight and also with molar volume along the lines indicated by the
Batchinski relation. The thermal conductivities have been found to vary inversely
with average molecular weight: In addition, liquid thermal conductivities have
been proportioned into atomic and ionic contributions each of which has been

separately correlated.
