Abstract

See full text

A pressure container for crystal production having excellent corrosion-resistance is provided. This pressure container produces crystals within the container using a seed crystal, a mineralizer, a raw material, and ammonia in a supercritical state or a subcritical state as a solvent. The pressure container has Ag present over the entire surface of at least the inner surface thereof in contact with the solvent. The Ag can be disposed by one or a combination of two or more among, for instance, Ag lining, Ag welding, and Ag plating. The mineralizer is preferably a fluorine mineralizer containing no halogen atoms other than fluorine.
