Electric-melting mullite
November 16, 2020
Mullite is a high-quality refractory raw material, and this type of mineral is rare.
Mullite is a mineral produced by aluminosilicates at high temperatures, and mullite is formed when artificially heating aluminosilicates. Natural mullite crystals are elongated needle-like and radiate clusters. The mullite mine is used to produce high temperature refractories. It is widely used as a thermal barrier coating in C/C composites and is widely used. Mullite AI2O3-SiO2 element system is a stable binary solid solution under normal pressure. The natural mullite with chemical formula Al2O3-SiO2 is very few, usually synthesized by sintering or electrofusion.
