Mullite Ceramics:
Mullite ceramics is a general term for a class of ceramics in which the main crystal phase is mullite (3Al2O3·2SiO2). If the mullite porcelain without glass phase is prepared from synthetic ultra-fine high-purity mullite powder, it is also called new mullite ceramic, that is, high-purity mullite ceramic.
