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.
Mechanical properties
The mechanical properties of the high-purity mullite ceramic sintered body are determined by the ratio of Al2O3/SiO2 and the microstructure, especially the mullite ceramics with an Al2O3 content of 68%. The flexural strength at 1300 °C is 570 MPa, and the fracture toughness Kic is up to 5.7MPa.Nm, which is 1.6 times higher than normal temperature.
