Abstract
The intensity vs. temperature functions of several selected reflections from originally twinned loucite crystals have been determined. These, together with the change in axial ratio c / a , are consistent with a single transformation at 605 ± 5°C with a direct change in space group from I 4 1 / a to Ia la3 d , and with a disappearance of twinning at the same temperature. The crystal structure of the cubic high-temperature polymorph has been refined with intensity data measured at 635 ± 5°C.This publication has 2 references indexed in Scilit:
