Abstract:
1. A hot isotropic pressure device comprising: a high-pressure container which accommodates a subject treatment material; a gas impermeable casing which is disposed inside the high-pressure container so as to surround the subject treatment material; a heating unit which is provided inside the casing and forms a hot zone around the subject treatment material so as to perform an isotropic pressure treatment on the subject treatment material using a pressure medium gas inside the hot zone; a cooling unit which guides the pressure medium gas, cooled while being guided from the upper side toward the lower side at the outside of the casing, into the hot zone so as to cool the hot zone; and a gas introducing unit which is provided in the cooling unit, wherein the gas introducing unit guides the pressure medium gas, cooled at the outside of the casing, from a lower portion of the high-pressure container to an upper portion of the hot zone without any intersection with the pressure medium gas inside the hot zone, and introduces the pressure medium gas into the hot zone.
