Hexagonal gallium orthophosphate crystals with sizes of 6X4X1mm3 have been obtained by spontaneous nucleation using the slow cooling method from X2O-3MoO3 fluxes with X=Li, K. Infrared transmission measurements revealed samples without significant hydroxyl groups and thermal analyses have pointed out the total reversibility state of the phase transition alpha-quartz GaPO4{left-right arrow}beta-cristobalite GaPO4.
