| 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 AIPO4 and GaPO4. The solid solution crystals Al1-xGaxPO4 are easy to grown and have better optical quality than those of AlPO4 crystals under the same conditions. A phase transition temperature Tα-β is 587 ± 3 °C for x = 0.12. Cell parameters, and elastic, piezoelectric, and dielectric constants are given. |
