Ceramic fiber paper is a paper refractory product made of ceramic fibers, also called aluminum silicate fiber paper. Ceramic fiber paper is a high-temperature refractory material, usually made of inorganic oxide fibers, mainly including Al2O3, SiO2, and ZrO2, and certain additives are added to make it compact. Ceramic fiber paper can not only be used as thermal insulation material for the inner wall of furnace lining and sealing material for high-temperature appliances, but also can be used as thermal insulation material for aviation and aerospace, and has a wide application prospect.
