Calcined talc powder is a high-performance material processed from natural talc ore through sintering at elevated temperatures. This premium-grade product maintains exceptional whiteness 94-95% even under extreme conditions at 1300°C, making it ideal for high-temperature applications. The calcination process enhances the material's thermal stability and mechanical properties, significantly improving the toughness and thermal resistance of ceramic bodies and other composite materials. With its excellent heat resistance and uniform particle distribution, calcined talc powder effectively reduces deformation, increases dimensional stability, and enhances the overall durability of finished products across various industrial applications including ceramics, plastics, rubber, and coatings.
