Abstract
PURPOSE: To obtain artificial rock crystal almost free from lattice defects such as dislocation by holding an artificial rock crystal growing system at a temp. below the growing temp. for a fixed time, raising the temp. to the growing temp., and carrying out heat treatment to relieve the strain when the crystal is grown by a hydrothermal synthesis reaction.
CONSTITUTION: Starting material rock crystal is put in a lower part of an autoclave, and seed crystal is suspended from an upper part. The growing temp. is determined with a temp. difference so that the temp. of the upper part is made lower than that of the lower part. The upper and lower parts are held at a temp. below the growing temp. for a dixed time to well relive the strain of the seed crystal, and then heat treatment is carried out so that the growing temp. is simultaneously attained with the temp. difference. Both the crystals are melted to liq. phase, and the lower rock crystal is carried upward by a heat convection, supersatd., deposited on the seed crystal, and grown.
