摘要

Process for growing single crystals made of metal orthophosphates of the crystallographic point group 32, especially GaPO4 or AlPO4 uses a crystal nucleus having two rod- or plate-like angled sides which tensions the main growing region and is arranged in the single crystal. Preferred Features: The crystal nucleus is obtained monolithically from the single crystal. A single crystal, preferably made of GaPO4, AlPO4, FePO4, GaAsO4, AlAsO4, SiO2 or GeO2, is used for the crystal nucleus.
