Thermal Ceramics Kaolite 3300 High Temperature Insulating Castables
Categories:	Ceramic; Oxide; Aluminum Oxide
Material Notes:	Kaolite 3300 is a high strength bubble alumina, lightweight castable with a high-purity binder. It contains less than 0.2% iron oxide and 0.5% silica. Kaolite 3300 is recommended for transfer lines to secondary ammonia reformers, and other applications where resistance to hydrogen atmospheres and silica pickup is critical. Features: Low thermal conductivity Reduction of the quantity of heat storage and heat transfer produce significant savings in fuel consumption Temperature range up to 3300°F (1816°C) Information provided by Thermal Ceramics Data has not been recently verified. Please contact manufacturer for current information.
