PROCESS FOR LOWERING THE WATER CONTENT OF PIEZOELECTRIC GAPO4 CRYSTAL ELEMENTS AND CRYSTALS PRODUCED THEREBY
摘要
To reduce the water content in piezoelectric GaPO4 crystal elements, it is proposed that each GaPO4 crystal element be cut as a whole from a single growth zone of a GaPO4 crude crystal ingot and be free of zone boundaries. <IMAGE>
