Gallium nitride is direct bandgap semiconductor, which is available in powder, wafer, monocrystal, ingot, piece, rod and so on. It is hexagonal crystal. GaN starts to decompose at 1050℃ (2GaN(s)=2Ga(g)+N2(g). It slowly volatilize in nitrogen or helium when temperature is 1000℃, which prove its stability at relatively high temperature. GaN does not decompose in cold water or hot water, dilute or concentrated hydrochloric acid, nitric acid and sulfuric acid, cold 40% HF. It is stable in cold concentrated alkali, but dissolve in alkali when heating. Gallium metal, gallium phosphide or gallium arsenide is the raw material.
