Magnesia brick - AOD

Physical & Chemical Specification

Sintered magnesia bricks MZ89-MZ98 choose one or two kinds of dead-burned magnesite withcorresponding content of Mg0 as the raw material. lt has high density, low apparent porosity,large dimension of periclase crystal and better high-temperature volume stability,better-temperature strength and anti-slag performance.


Magnesia chrome bricks

The burnt magnesia chrome bricks are made out of high-quality magnesite and chrome orefine charge mixture.
lt has good high-temperature performance and metallurgical slag corrosion resistance isstrong. It can resist the corrosion of cement clinker. It’s widely used in the electric furnacelining for steel-making, nonferrous metallurgical furnace and cement rotary kiln etc.
