Product Description
Precision casting grade mullite powder high strength easy to clear shell Mullite sand
Mullite, an aluminum silicate refractory, is generally used in stainless steel precision casting processes. The refractoriness is about 1750 degrees, the higher the aluminum content in the mullite, the lower the iron content, and the smaller the dust, the better the quality of the mullite product. Mullite is kaolin sintered at high temperature.
Mullite Sand Features:
1. High refractoriness.
2. High aluminum content and low iron content.
3. High bulk density.
4. The thermal expansion coefficient is small.
5. Physical and chemical properties are stable.
6. Fully calcined.
7. Less dust content.
8. Size standard.
