Chemical formula: 3Al2O3 · 2SiO2. Colorless. Red or blue with rose-containing impurities. Orthorhombic, a columnar or needle-like crystals. Melting temperature of about 1910 ℃. alluvial garnet gbrasives Generated calcined clay, high alumina raw material (such as kyanite, andalusite, sillimanite) and ceramics. Is the main component of clay brick, high alumina brick and porcelain, Moore produced in Scotland Island and other places. Can also be fused legal system. See kyanite and andalusite.
Refractoriness: 1800 ° C while still stable, cubic boron nitride 1810 ° C and a liquid phase decomposition of corundum mullite
Mullite is a high-quality refractory materials, it has expanded uniform, excellent thermal shock resistance, high load softening point, a small high-temperature creep, hardness, chemical resistance and good features, mainly high purity electricity fused mullite, green silicon carbide fused mullite general, all-natural mullite sintered bauxite concentrate and the light burned mullite.
