Fine and nearly monosized stress-free single crystals can be prepared by hydrothermal crystal growth under controlled nucleation density. The powder preparation method basically comprises (1) the preparation of an x-ray amorphous mixture of starting materials, (2) heat treatment of the mixture for nucleation and (3) crytal growth in the hydrothermal condition.
