Sillimanite Brick
Sillimanite brick is a firebrick with good properties prepared by high temperature firing or mud pouring of silicalite minerals. Silicalite is calcined at high temperature and converted into Mullite and free silica. Generally, high temperature firing method and mud pouring method are used for production.
1.Good thermal stability
2.Low thermal expansion rate
3.Good anti- chemistry eroded performance
4.High temperature resistance
5.High softening temperature under load
Sillimanite Brick Description
Sillimanite brick is a firebrick with good properties prepared by high temperature firing or mud pouring of silicalite minerals. It is a kind of natural refractory mineral, which has the characteristics of low thermal expansion rate, resistance to the erosion of metallurgical slag and various glass liquids, and good wear resistance at high temperature.
The Application Of Sillimanite Brick
Sillimanite brick have better physiochemical properties than high alumina bricks, they are mainly used in glass tank furnace throat, blast furnace lining, furnace throat, ceramics industry kiln furniture.
As sillimanite brick have good high temperature thermal stability, good resistance to glass liquid corrosion, they are usually used at glass industry feeding canister, feeder, tube drawing machine.
As sillimanite brick have very good high temperature performance and higher refractoriness. Sillimanite brick is widely used in metallurgy, chemical and building materials industries.
