Indium Telluride (II'): Transitory Intermediate Phase in the Transformation InTe(II) to InTe(I).
The high-pressure cubic metallic form of indium telluride, InTe(II), transforms at 1 atmosphere to a new transitory polymorph, designated InTe(II'), which, in turn, transforms to the stable tetragonal polymorph InTe(I). The new polymorph is apparently tetragonal with unit-cell dimensions a(0) = 6.06 A, c(0) = 6.55 A. The transformation rates of InTe(II) to InTe(II') and of InTe(II') to InTe(I) are dependent on both time and temperature; the former is very rapid above 60 degrees C and the latter is very rapid above 125 degrees C.
