Product Description

Mullite can be divided into sintered mullite/fused mullite
Natural calcination mullite series products use huaibei high quality characteristic coal mine as raw materials made by calcination at a high temperature
Product has the texture density, high hardness, expansion coefficient, excellent wear resistance, thermal properties and good chemical stability. It is mainly used in metallurgy, building materials, chemicals, refractories, military, and other industries.
Fused mullite
The mullite melted with high purity raw materials has a low porosity, high density, low impurity and other characters and can be processed into different size particles, powders and micro powders
