Abstract
Crystalline GaPO4 was prepared in a hydrothermal bomb at 200° to 300°C. It was found to be isostructural with the berlinite form of AlP04. Thermal analysis and high‐temperature X‐ray techniques were utilized to show that the analogy extends to some of the polymorphic forms of AlPO4 as well. Three forms of GaPO4, corresponding to the berlinite, high‐cristobalite, and low‐cristobalite forms of the A1PO4 system, were observed. No evidence was found to indicate the existence of a tridymite form.Keywords
