Product details:location : Home > Products > Mullite Refractory

Mullite brick is refractory product made of best quality mullite. This product is of good chemical stability, high loading softening temperature, and good thermal shock stability, hence important refractory material in metallurgy, construction material, electron etc.

Composed of compound mullite, the brick are processed through moulding under high pressure and sintering at high temperature, with feature of strong strength, steady bulk at high temperature and small creep rate, which are available for hot blast stove of large and middle size.

Features
1.High insulating properties
2.Strong compressive strength
3.Low heat storage
4.High purity
5.Tight dimensional tolerance
6.Energy saving
7.Low impurities
