Abstract

The present invention relates to a pressure container for crystal production having excellent corrosion-resistance. This pressure container produces crystals within the container using a seed crystal, a mineralizer, a raw material, and ammonia in a super critical state and/or a sub-critical state as a solvent. The pressure container has Ag present over the entire surface of at least the exposed inner surface thereof. 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.
