FIELD: powder metallurgy, namely equipment and processes for treating materials in chemically active medium at high temperature and pressure values, possibly dissolving of ceramic materials and their structural conversions.
SUBSTANCE: isostatic apparatus includes fluid-tight container connected with unit for gas supply. Induction heater and working chamber with open upper end are arranged in said container. Working chamber is in the form of vessel with doubled walls and bottom between them. Isostatic apparatus is provided with heat-insulation chamber whose wall is arranged in interval between walls of vessel. Ceramic members are removed out of metallic articles due to heating ceramic members in heated pressurized alkali solution.
EFFECT: enlarged operational temperature range of isostatic apparatus, intensified process of leaching.
