Thermal Ceramics Kao-Tab HDHS-98 High Alumina Castables
Categories:	Ceramic; Oxide; Aluminum Oxide
Material Notes:	Kao-Tab HDHS-98 is a very high purity, 98% alumina castable with high hot strengths. Excellent for hydrogen atmospheres needing high-purity or high temperature applications in the ion and steel, chemical processing, and cement industries. Features: Designed for supercritical applications Specially enhanced high alumina chemistries that allow Kao-Tab to outperform conventional castables Applications: Cat cracker transfer lines where more abrasion resistance is needed Secondary ammonia reformer linings where low silica is desired Recovery boiler Upper furnace walls Recovery/cyclone boilers Lower furnace walls and floor Cyclone boilers Information provided by Thermal Ceramics Data has not been recently verified.
