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.

The color is white and the size is regular, which integrates fire resistance, heat insulation and heat preservation. It does not contain any binding agent. It can maintain good tensile strength, toughness and fiber structure when used in neutral and oxidizing atmosphere for a long time. Temperature resistance is 950-1400 ℃.
