Aluminum silicate wool, also known as ceramic fiber, consists of amorphous fibers produced by melting a combination of Al₂O₃ and SiO₂, usually in a weight ratio of 50:50. Aluminum silicate fibers show a high temperature resistance in continuous use with temperatures up to 1400℃. Many people in the market refer to aluminum silicate fiber board as fireproof board and thermal insulation board; and call aluminum silicate fiber blanket as thermal insulation blanket, thermal blanket, fireproof blanket, etc., although their names are different, they are essentially refractory aluminum silicate fiber materials. All aluminum silicate fiber products are characterized by low thermal conductivity, low heat storage, excellent thermal shock resistance, low weight and superior corrosion resistance. Aluminum silicate fibers are used for insulation, packing, smoke stack filters, gaskets, plastic reinforcement, and fireproof panels.
