METHOD OF OBTAINING GALLIUM NITRIDE Russian patent published in 2014 - IPC C01B21/06 B22F9/16 B22F3/23 

Abstract RU 2516404 C2

FIELD: chemistry.

SUBSTANCE: invention relates to production of gallium nitride and can be used in electronic, aerospace, hard alloy, chemical branches of industry to obtain highly pure nitride, applied for manufacturing products, which possess high luminescent properties, chemical and radiation stability, thermal stability, stability in aggressive media, stability of physical properties in wide ranges of temperature. Method of obtaining gallium nitride powder includes: preparation of exothermal mixture, consisting of element to be nitrided, gallium, inorganic azide - sodium azide and galloid salt - ammonium fluoride or ammonium chloride, and ignition of mixture in nitrogen environment under pressure, with obtained powder being used for preparation of exothermal mixture with sodium azide and galloid salt, carrying out four-fold synthesis and each time exothermal mixture is prepared from powder, obtained at the previous stage, with sodium oxide and galloid mixture.

EFFECT: invention provides final product output about 100%.
