PRODUCTION METHOD OF NITRIDE CRYSTAL, DISSOLUTION AND TRANSPORTATION ACCELERATOR FOR AMMONOTHERMAL RAW MATERIAL, AND GROWTH ACCELERATOR FOR NITRIDE CRYSTAL

摘要

PROBLEM 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. SOLUTION: 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. COPYRIGHT: (C)2011,JPO&INPIT
