Explore: Mullite

Mullite or porcelainite is a rare silicate mineral formed during contact metamorphism of clay minerals. It can form two stoichiometric forms: 3Al2O32SiO2

platelet mullite and highly crystalline cristobalite: 3 Si3Al4O12 → 2 (3 Al2O3 . 2 SiO2) + 5 SiO2 Finally, at 1400 °C the "needle" form of mullite appears

mineral mullite, the only thermodynamically stable intermediate phase in the Al2O3-SiO2 system at atmospheric pressure. This also called '3:2 mullite' to

additional coatings that are more oxidation resistant, such as alumina or mullite. The bond coat is an oxidation-resistant metallic layer which is deposited
