Inexpensive methd for coating the interior of silicoa growth ampoules with pyrolitic boron nitride

(2004)

Abstract

An inexpensive method was developed for coating the interior of silica ampoules with hexagonal boron nitride. An aqueous solution of boric acid was used to coat the ampoule prior to drying in a vacuum at 20OoC. This coating was converted to transparent boron nitride by heating in ammonia at 1000?C. Coated ampoules were used to achieve detached solidification of indium antimonide on earth.
