Investment casting mullite powder Mullite sand for precision casting Casting powder
Description:
Mullite is a high-quality refractory raw materials, this kind of mineral is relatively rare. Mullite is a mineral formed at high temperatures from aluminosilicate, which is formed when Aluminosilicate is heated artificially. Natural mullite crystals are elongated needle-like and radiate in clusters. Mullite mines are used to produce high-temperature Refractory. It is widely used as thermal barrier coating in C/C composites. Mullite AI2O3-SiO2 is a binary solid solution which is stable under atmospheric pressure. The natural mullite with the chemical formula AI2O3-SiO2 is very few.
