Abstract:

Bulk cubic gallium nitride is made by charging into a reaction vessel to a fill of 25-95 having a temperature difference between its ends of at least 1 deg C a gallium precursor, sufficient amount of an acid mineralizer to form product zinc blende gallium nitride, and sufficient amount of ammonia to at least solubilize the precursor sealing the reaction vessel heating contents of the reaction vessel to at least 150 deg C while autogenously pressurizing contents of the reaction vessel to at least 500 psi for a duration sufficient to form the product zinc blende gallium nitride cooling contents of the reaction vessel and removing from the reaction vessel the product zinc blende gallium nitride.
