Ceramic fiber boards are categorized based on their composition, temperature resistance, and applications. The main types include: 1. Standard Ceramic Fiber Board, used for general thermal insulation in furnaces and kilns. 2. High-Alumina Ceramic Fiber Board, suitable for high-temperature applications due to its excellent thermal stability. 3. Zirconia Ceramic Fiber Board, known for its high-temperature resistance and used in severe environments. 4. Alkaline Earth Ceramic Fiber Board, resistant to chemical attack and used in corrosive environments. 5. Low Biopersistent Ceramic Fiber Board, designed for applications where minimal fiber release is crucial. These boards are used in various industries such as aerospace, automotive, steel, and chemical processing for thermal insulation, fire protection, and energy conservation.
