Zircar Refractory Composites RS-99-45 Refractory Sheet

ZRCI Refractory Sheet Type RS-99-45 is comprised of 99% alumina. This "All-Alumina" material is strong, uniform, rigid, refractory structure composed of alpha alumina fibers and high purity inorganic binders. Type RS-99-45 has a high purity alumina bond making it well suited for use in high vacuum and reducing environments where silica cannot be tolerated, such as power metal and MIM furnaces with H2 atmospheres. It also has high electrical resistivity at elevated temperatures allowing it to be used in direct contact with resistance heating elements. It exhibits superior hot strength and dimensional stability to 1650°C (3000°F).Information provided by ZIRCAR Refractory Composites, Inc. (ZRCI)
