Mullite powder is made from the natural high-quality bauxite,it’s calcined temperature over 1750°C. Mullite powder is an ideal raw material for the following refractory products like a variety of shaped and unshaped refractory, advanced ceramic asanitary ware body, precision casting models and so on.FeaturesHardness, high bulk densityStable Physicochemicalfull calcinedHigh aluminum contentLow iron contentLow dust content.Small index of high temperature creepGood resistance to chemical corrosion.
Features and advantages:
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.
