Thermal Ceramics' Kao-Tab® castable line, based on chemically and thermally stable tabular alumina aggregate, has very low levels of alkali and titania impurities, as well as very small amounts of silica. This makes them very resistant to reducing atmospheres and also produces high hot strengths. The company offers four castables in the high alumina castable family: Kao-Tab 95 and Kao-Tab 95 Gun 95% alumina castables designed for casting and gunning, respectively; Kao-Tab SR, an 88% alumina castable designed for placement by gunning or hand ramming; and Kao-Tab HDHS-98, a very high purity, 98% alumina castable with high hot strengths, used for hydrogen atmospheres in the chemical processing industry or high-temperature applications in the iron and steel, cement, and copper industries.
