METHOD FOR PRODUCING NITRIDE CRYSTAL, NITRIDE CRYSTAL AND APPARATUS FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently growing a high-purity nitride crystal with low oxygen concentration by means of an ammonothermal method.

SOLUTION: The method for producing a nitride crystal includes: bringing a reactive gas which reacts with ammonia to produce a mineralizer into contact with ammonia in a reaction chamber 1 or in a closed circuit connected to the reaction chamber 1 to produce a mineralizer; and in the presence of the ammonia and the mineralizer, growing a nitride crystal from a crystal growth raw material 5 comprising a nitride placed in the reaction chamber 1 by an ammonothermal method.
