Ceramic Fiber Board
Ceramic Fiber Board is made of high purity alumina fibrous and alumina powder,to be formed and fired in special equipment with advanced patent process, can withstand temperature up to 1700 celsius.
- The kiln wall of industrial kiln, is lined with refractory layer and insulation layer, which can be directly calcined by open flame
- Lining of high-temperature kiln, kiln car, furnace door baffle, the temperature partition plate of kiln or furnaces.
- Insulation and heat preservation of high-temperature and high-heat equipment
- Heat insulation, fire prevention, sound insulation etc for aerospace and shipbuilding industry
- High temperature thermal insulation cover plate of polycrystalline crucible.
