Abstract
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 GaPO4 . The solid solution crystals Al1-xGaxPO4 are easy to grown and have b etter optical quality than those of AlPO4 crystals under the same cond itions. A phase transition temperature T(alpha-beta)is 587 +/- 3 degre es C for x = 0.12. Cell parameters, and elastic, piezoelectric, and di electric constants are given.
