Systems and methods for synthesis of gallium nitride powders

A method of producing high quality GaN powder by combining high purity gallium and high purity ammonia in a tube reactor under controlled conditions. A reaction between the ammonia and gallium under the controlled conditions produces a porous gallium melt and to a full reaction, yielding high purity...

Zusammenfassung:A method of producing high quality GaN powder by combining high purity gallium and high purity ammonia in a tube reactor under controlled conditions. A reaction between the ammonia and gallium under the controlled conditions produces a porous gallium melt and to a full reaction, yielding high purity crystalline GaN powders with a stoichiometric nitrogen concentration and a hexagonal wurtzite structure.
