摘要：

The application of gallium phosphate (GaPO4) for piezoelectric devices at high temperatures is limited due to the OH- content of the crystals. The solvents used in the established hydrothermal growth of these crystals are considered the source of these defects. Thus, their complete exclusion should be possible by using water-free solvents. Single crystals of GaPO4 have been grown from the NaCl flux by cooling from about 900 to 600 degrees C. This paper reports on the first results referring to such flux-grown GaPO4 crystals.
