Design and production of crucible isostatic molds, graphite crucible and other materials isostatic molding dies, cold isostatic pressing is a crucial ceramic forming technique. It involves compressing powder into shape at room temperature through the transmission of isotropic pressure via a fluid medium. Compared to conventional forming techniques, isostatic pressing results in higher green density, up to 5% to 15% higher than that of conventional molding, and uniform green density, making it suitable for products with high length-to-diameter ratios such as cylindrical ones. Additionally, isostatic pressing products exhibit excellent properties, thus the technology is crucial in the preparation of special ceramics and has been successfully applied in the production of large, complex ceramic products like ceramic antenna covers, vacuum interrupter ceramic tubes, thermocouple protective ceramic sleeves, ceramic pipes for oil drilling made of alumina or zirconia, transparent ceramic sleeves for high-pressure sodium lamps, high-voltage ceramic insulators, spark plugs, and carbon graphite products.
