Material Notes:
Thermal Ceramics was first to introduce insulating firebrick (IFB) to the industry in the 1930’s. The IFB are manufactured with a slurry casting process which creates a network of microporosity which produces low thermal conductivity and good thermal shock characteristics. This process produces brick that are some of the most efficient insulators available in the market. The anorthite mineralogy (CaO, Al2O3, 2 SiO2) of these low temperature IFB gives them excellent strength at operating temperatures and resistance to corrosive alkali environments. Features: Extremely low “K” factors Low densities Low heat storage Excellent strength at room and high temperatures Excellent resistance to alkali attack Excellent service in applications involving special atmospheresApplications: Backup insulation for carbon baking furnaces Backup insulation in aluminum electrolytic cells Electrical kilns for industrial and hobby use Backup insulation for blast furnace stove linings Linings for carbonizing furnaces Forge furnace linings Heat transfer liningsInformation provided by Thermal CeramicsData has not been recently verified.
