ABSTRACT

Optical properties and X-vay diffraction data are listed
for various inorganic fluoride and chloride compounds. This
publication extends and replaces ORNL-i7i2, Properties of Some
Inorganic Filuoride and Chloride Compounds, by T. N. McVay and
G. D. White.

 

 

INTRODUCT ION

Optical and X-ray diffraction data have been collected for
many compounds whose existence was not known prior. to their dis-
covery incidental to the phase equilibrium studies made in the
High Temperature Section of the Chemistry Division. A few com-
pounds are listed and mentiomed in the footnotes whose initial
discovery was not made at ORNL; however, the original optical
measurements on these compounds were made by H. Iusley,

T. N. McVay, and G. D. White of the Ceramics Laboratory,
Metaliurgy Division.

The standard X-ray diffraction patterns included herein
were derived, in general, from the same samples on which the
optical data were taken. Standard patterns were made from
powder samples with a Norelco~Philiips high angle diffracto-
meter, using Cu K, filtered radiation from a General Electric
CA-7 X-ray tube. The diffractometer was equipped with a Geiger
Muiier tube counting arrangement. The X-ray data have not been
corrected for absorption. Values for interplanar distances
(d, measured in Angstrom units) and relative intensities of
diffracting maxima conform to the conventions used in the ASTM
X-ray diffraction data cards.

The refractive indices of the compounds included are be-
lieved to be precise to * 0.003; the optic angles of biaxial
crystals were estimated.
This publication is divided into Part I (optical properties)
and Part II (X-ray diffraction data). The three strongest
X-ray lines accompany the optical data of each compound for
which ASTM X-ray diffraction data are not availabkle, if those
X-ray data were derived at ORNL. X-ray diffraction data in
Part II are separated according to the purity of the samples

used for standards. Patterns for the compounds in the first
section were derived from single-phase samplies of known
chemical analysis which had met optical standards. In the

second section are listed data on compounds whose purity has
not been absoclutely established.
