Standard X-ray Diffraction Powder Patterns

Indium sulfide, ln z $ 3
Sample
The In 2 S 3 was made by W.S. Brower by heating the
elements in a sealed silica tube at 460 °C for
sixteen hours and at 880 °C for six hours.
Color
Unground: dark grayish red
Ground: strong reddish brown
Structure
Tetragonal, I4i22 (98), Z=16. The structure was
studied by Rooymans [1959] and by Goodyear and
Steigmann [1961].

Polymorphism
Hahn and Klinger [1949] found that a low temper
ature form transformed irreversibly at about
330 C to a high form which they indexed as cu
bic with a few extra non-cubic lines.
