Ceramic fiber insulation comes in several types, each with specific applications due to their unique properties. Types include: 1) Alumina Silicate Fibers, used for high-temperature insulation in furnaces and kilns; 2) Calcium Silicate Fibers, suitable for moderate temperature applications such as fireproofing and thermal insulation; 3) Mullite Fibers, known for their high strength and used in aerospace and automotive industries; 4) Zirconia Fibers, resistant to extreme temperatures and used in nuclear applications; 5) Alumina-Zirconia Fibers, offering high thermal stability and used in advanced industrial furnaces. Each type is chosen based on the temperature resistance, chemical stability, and mechanical strength required for the application.
