An x-ray powder diffraction study of the high temperature phase transitions in -quartz-type AlPO4-GaPO4 solid solutions

Al1-xGaxPO4 solid solutions (x = 0.,0.7) with the -quartz-type structure were investigated up to 1208 K by x-ray powder diffraction. The composition Al0.7Ga0.3PO4 exhibits almost simultaneous transitions to the -quartz and -cristobalite forms at close to 1050 K. The tendency towards the -quartz type...
