Also known as high fire porcelain, because the formula contains more kaolin and less feldspar and other flux, its porcelain forming temperature is higher, generally above 1300 ° C. Because its microstructure contains more mullite crystal, less glass phase, and the hardness of porcelain and glaze is higher than that of other ceramics, it is called. high fire porcelain has high mechanical strength, good chemical stability, thermal stability and electrical insulation performance, and its water absorption is close to zero. It is used for chemical porcelain, electric porcelain and high-grade daily fine porcelain.
