High temperature refractory ceramic

Product Description

1. Art of Technology: The Aluminum Oxide Ceramic Foam Insulation Material was manufactured based on multiple technologies of Material Science, Condensed Matter Physics and Surface/ Interface science with the Nano Particle of Alumina oxide. According to the production technology of highly concentrated suspension process, surface modification of nano-particles and Sol-Gel casting, the Aluminum Oxide Ceramic Foam Insulation Material, with ultra-light weight, excellent compressive and flexural strength and high temperature resistance, was developed. The application temperature can be as high as ***0°C, which is not available for aluminium silicate, polycrystal mullite, alumina based ceramic fiber or any other light weight refractory brick in the market. 2. Characteristics: (1) High Purity: Al2O3 > *5%; (2) Application temperature: up to ***0°C (3) High strength: much longer lift time than RCF. (4) Ultra-low density: 0.**0.5 g/cm3 (5) Low Thermal Conductivity and Linear Thermal expansion coefficient; (6) Fiber free: harmless to people in the production and using process. (7) Great Thermal Shock Resistance: can be used for quickly heating and cooling. 3. Applications: (1) ***0 °C ****0°C laboratory or industrial furnace lining; (2) Electric or gas heating furnace lining; (3) Kiln cars lining; (4) All applications when temperature achieved ***0°C (5) High temperature field with H2, CO or other reducing / oxidizing atmosphere.
