History and Application of Ceramic Fiber

- Jan 04, 2018-

Ceramic fiber first appeared in 1941, the Barb Wilcox Company uses natural kaolin clay, through the electric arc furnace melting injection, to manufacture fibers. In the late 1940s, the two companies produced series of aluminium silicate fibre, and applied them in the aviation industry for the first time; In the 1960s, the United States developed a variety of ceramic fiber products, and used in wall lining of industrial furnace. In the 1970 s, ceramic fiber started be Started be produced and used in China and its application technology got rapid promotion in the 1980s, but the temperature used mainly under 1000 ℃. Application technology at that time is relatively simple and laggard. After entering the 1990s, with the application of containing zirconium fiber and polycrystalline alumina fiber, service temperature reached to 1000 ℃ ~ 1400 ℃. However, due to the poor product quality and laggard application technology, application field and application way have been limited. There are some examples: Polycrystalline alumina fiber cannot be made into fiber blanket; Product specification sheet is given priority to loose cotton, fiber blocks; Although insulating temperature of electrical appliances has increased, because of the poor intensity, limiting the scope of use and shortening the service life. 

Containing zirconium fiber is a widely applied and low-cost aluminum silicate fiber, which produced by melting. It can be used to build the heat-surface whole fibers liner of various thermal furnace. In terms of quality and application and development, current domestic products are still relatively backward. Now chrome fiber appeared in the overseas, its service temperature is higher than containing zirconium fiber, China hasn’t report this aspect.
