Insulating mullite ceramic tube fire-proof ceramic tube
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.
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.
