refractory industrial custom made mullite ceramic crucible machinery parts supplier

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. This temperature increase, strength and toughness not only do not attenuate but increase greatly. In addition to SiC, it is unique in the existing high-temperature ceramic materials, which is also high. Pure mullite ceramics are excellent properties as high temperature materials.

Optical performance
Although the mullite crystal is not a cubic crystal system, it is only an orthorhombic system, but due to the small birefringence of light (only 0.012), a ceramic material having a certain transparency can be obtained under certain conditions. The high-purity ultrafine powder prepared by the alkoxide hydrolysis method can be obtained by vacuum sintering at 1750 ° C to obtain transparent mullite porcelain.
