Good Quality Mullite Sand/ Mullite Powder for Refractory Brick
Mullite Sand and Mullite flour for investment casting(16-30,30-60,60-80mesh)
Mullite is a series of aluminum silicate minerals used to produce high-temperature refractory. mullite is a kind of high quality refractory materials,it has the expansion uniformity,excellent thermal shock resistance,high load softening point,high temperature creep value is small,high hardness,good resistance to chemical corrosion, there are mainly high purity fused mullite, fused mullite sintered mullite, all natural bauxite concentrate and light mullite.
Features:
1. High refractoriness.
2. Aluminum content high, the iron content low.
3. High volume density.
4. Thermal expansion coefficients of small.
5. Physicochemical stability.
6. Fully calcined
7. Dust content low
8. The specification standards.
Advantages:
1. Easy out of shell.
2. No deformation.
3. No reduced scale.
4. Good brightness , Good finish .
5. Product rate is high.
