Production manner of nitride crystal, dissolved carrying accelerator and nitride crystal growth promotor of raw materials for nitride grain growth

摘要

PPROBLEM TO BE SOLVED: To provide a method for increasing the growth rate of nitride crystal by an ammonothermal method without employing high temperature and high pressure conditions. PSOLUTION: A nitride crystal is grown by an ammonothermal method in ammonia containing an ammonia pyrolysis catalyst 7 that does not corrode or dissolve supercritical ammonia. The ammonia pyrolysis catalyst 7 is the elemental substance of Ru, Rh, Pd, W, Re or Os or the alloy of one of Ru, Rh, Pd, W, Re, Os, Ir or Pt and other metals. PCOPYRIGHT: (C)2011,JPO&INPIT
