METHOD OF GROWING CRYSTAL OF BETA BARIUM BORATE

摘要

A method of growing optical quality beta barium borate crystals from a pure NaCl fluxed melt. The method comprises maintaining particular thermal field conditions throughout the melt and slowly cooling the melt to cause beta barium borate to crystallize from the melt. The rate of cooling may be at a rate of not greater than 3 DEG C per day. The method may utilize a seed crystal, suspended into the melt, so that the beta barium borate may crystallize on the seed crystal.
