Ceramic fiber products refer to the industrial products with the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical vibration resistance made of ceramic fiber as raw material, which are specially used in various high temperature, high pressure and wear environments.

Common ceramic fiber is also known as aluminum silicate fiber. Because one of its main components is aluminum oxide, which is also the main component of porcelain, it is called ceramic fiber. The use temperature of ceramic fiber can be further increased by adding zirconia or chromium oxide.
