What are the different materials used for ceramic fiber products?

Ceramic fiber products are made from various inorganic materials that can withstand high temperatures. The primary materials include alumina-silica fibers, mullite fibers, and alumina-zirconia fibers. Alumina-silica fibers are made from kaolin clay and alumina, offering good thermal insulation. Mullite fibers, derived from alumina and silica, provide higher strength and creep resistance. Alumina-zirconia fibers, made from a combination of alumina and zirconia, exhibit excellent high-temperature stability and resistance to thermal shock. These materials are chosen based on the specific application's temperature requirements, mechanical strength needs, and chemical resistance.
