The new piezoelectric solid solution aluminium gallium orthophosphate single crystals have been successfully developed for the first time in our laboratory by hydrothermal method. It has been demonstrated that these crystals are homogeneous, and isomorphous with AIPO 4 and GaPO 4 . The solid solution crystals Al 1‐x Ga x PO 4 are easy to grown and have better optical quality than those of AlPO 4 crystals under the same conditions. A phase transition temperature T α‐β is 587 ± 3 °C for x = 0.12. Cell parameters, and elastic, piezoelectric, and dielectric constants are given.
