Abstract
To obtain large, high-quality crystals of a metal orthophosphate, in particular GaPO or AlPO , from a nutrient solution with the use of seeds, a seed crystal is used having at least two rod- or wafer-shaped legs which form an angle with each other and define a main growth region, and which are positioned eccentrically in the single crystal grown. Contagious faces of two seed legs, which have been chosen for crystal growing, enclose an angle <180°. In this way the yield of the high-quality crystal region will be increased.
