Morgan Advanced Ceramics Kaogun® 30 Thermal Ceramic
Categories: Ceramic; Oxide

Material Notes: Gun installation. Kaogun 30 is a thermally stable 3000°F (1649°C) gunning mix incorporating a high-purity, calcium-aluminate cement designed for low rebound. The combination of bauxite and calcined kaolin grain sizing produces thermal stability throughout the temperature range . Typically used in reheat furnace roof and side wall repairs and forging furnace linings.
