Mullite or porcelainite is a rare silicate mineral formed during contact metamorphism of clay minerals.It can form two stoichiometric forms: 3Al 2 O 3 2SiO 2 or 2Al 2 O 3 SiO 2.Unusually, mullite has no charge-balancing cations present. As a result, there are three different aluminium sites: two distorted tetrahedral and one octahedral.. Mullite was first described in 1924 for an …
Mullite is a mineral produced by aluminosilicate at high temperature, and mullite is formed when aluminosilicate is artificially heated. It is mostly used as a thermal barrier coating in C / C composite materials and is widely used. Mullite can be used in refractory materials, ceramics, metallurgy, casting, electronics and other industries.
Mullite is a high-quality refractory raw material, this type of mineral is relatively rare. Mullite is a mineral produced by aluminosilicate at high temperature, and mullite is formed when aluminosilicate is artificially heated. It is mostly used as a thermal barrier coating in C / C composite materials and is widely used.
Mullite is generally represented as 3Al 2 O 3 ⋅2SiO 2 (i.e. 60 mol% Al 2 O 3). But in reality, it is a solid solution that has the equilibrium composition limits of 60–63 mol% Al 2 O 3, below 1600 °C. Synthetic Mullite. Different starting materials and preparation techniques are used to produce synthetic mullite ceramics.
Mullite refractory brick is mainly made of mullite as high alumina refractory. Generally, the content of alumina is between 65% and 75%. In addition to mullite, the lower alumina contained a small amount of glass phase and calcite. Higher alumina also contains a small amount of corundum. Mullite bricks manufacturing has a high refractory degree ...
