Abstract
A method and apparatus for producing a Group III nitride in which the thermal decomposition of the nitrogen element-containing gas is suppressed to enhance the productivity. The method for producing a Group III nitride crystal, comprising: reacting an oxide or a metal of a Group III element under a heated atmosphere to form a compound gas of the Group III element; mixing a nitrogen element-containing gas at a temperature that is lower than that of the compound gas, with the compound gas; and reacting the nitrogen element-containing gas with the compound gas to form a Group III nitride crystal.
