Magnesia Bricks/fired magnesia bricks for cement and glass plant

Magnesia Bricks dense sintered magnesia is used as raw material for making regular magnesia bricks. The magnesia bricks with MgO

Dense sintered magnesia is used as raw material for making regular magnesia bricks.they have high refractoryiness and are resistang to corrosion and widely used in the checkers chamber of glass tank furnace ,lime kiln,non-ferrous matal netallurgical fumace,open hearth furnace,iron mixer,ferro alloy furnace,electric furnace and so on.the magnesia bricks with MgO content over 95% are produced with magnesia made by two-step burning process or electro fused magnesia and fired under high temperature,they processhigh directbonding rate and strong corrosion resistance ability and are widely used in various kinds of high temperature kilns and furnace.

we can provided other kinds of brick too.
