The first is production of fused products. This process involves using an electric arc furnace to melt the refractory raw materials, then pouring the melted materials into sand-forming molds. Another type of refractory process is ceramic fiber production. In this process, calcined kaolin is melted in an electric arc furnace.
Kaolin is widely used in the production of ceramics and construction materials, where it enhances the strength, durability, and workability of products like bricks, tiles, and cement.
It is produced by heating kaolin, a natural clay mineral, to temperatures typically between 650°C and 750°C. At such temperatures, the kaolin is dehydroxylated, transforming from kaolin (Al 2 Si 2 O 5 (OH) 4 or AS 2 H 4) to metakaolin (Al 2 Si 2 O 5 or AS 2). This process results in a disordered structure and a highly reactive, amorphous ...
