Ceramic fiber is a kind of fibrous lightweight refractory materials and the main chemical composition of it is aluminum silicate. According to its mineral composition, it can be divided into two kinds: glass fiber and Polycrystalline fiber. Glass fiber material is formed by molten liquid flow in the cooling of an amorphous solid fiber; Colloid injection is usually used to form fiber, through high temperature calcination, polycrystalline fiber is formed.
Ceramic fiber is widely used in all kinds of furnaces of high temperature resistant and heat-insulated materials. Due to its bulk density is much lower than other refractory material, thermal storage is little, and heat insulation effect is obvious. As lining material, it can greatly reduce the energy loss thermal kiln. In the aspect of energy saving, it has brought a revolution for furnaces. On the other hand, its application technology and method also have brought a revolution for thermal furnace masonry.
