PREPARATION OF GALLIUM NITRIDE POWDER USING TRANSITION METAL CATALYST

摘要

PURPOSE: A preparation of gallium nitride(GaN) powder using transition metal catalyst is provided, which has improved crystallinity increased reaction rate and high yield. CONSTITUTION: The preparation of gallium nitride(GaN) is characterized in that a powder or net-typed transition metal catalyst such as Ni, Co, Pt and Pd is used in a conventional GaN powder produced from gallium and ammonia in a temperature of 900-1200C, followed by extracting and refining with an inorganic acid such as HCl, HNO3 and H2SO4.
