METHOD FOR PRODUCING NITRIDE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing a nitride crystal excellent in quality and conductivity through enhancing a growth rate and improving a utilization efficiency in raw materials by controlling a condition of crystalline raw materials used for producing the nitride crystal by an ammonothermal process.SOLUTION: The method for producing a nitride crystal in which a nitride crystalline raw material 8 is charged in a raw material charging area 9 in a reaction vessel 20 and a crystal growth is carried out in the reaction vessel 20 in the presence of a supercritical and/or subcritical solvent, in which the crystal growth is carried out by charging the nitride crystalline raw material 8 in the raw material charging area 9 in a bulk density of 0.7 to 4.5 g/cm.
