Applications of Ceramic Fiber Products

Ceramic fiber is a type of new lightweight refractory material developed in 1960s. According to the shape and structure, it belongs to amorphous (glassy) fiber. It is made of hard clay clinker or industrial alumina powder and silica stone synthetic materials as the raw materials by melting in an electric arc furnace or resistance furnace and blowing or spinning into fiber with compressed air. It is mainly composed of 30%-55% Al2O3 and SiO2. Ceramic fiber can be further made into blanket, felt, board, paper, and rope as well as prefabricated blocks.
