Ceramic fiber cotton is made of high-purity clay clinker, alumina powder, silicon powder, chrome sand, and other raw materials that are melted at high temperatures in the furnace to form a fluid, and then blown with compressed air or made into a fiber shape with a spinning machine, and ceramic fiber cotton is formed by collecting cotton. Fiber cotton can be further processed into fiber blankets, boards, paper, cloth, ropes, and other products.
