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

Using special grade high alumina bauxite clinker, high grade magnesia, fused magnesia and graphite as raw materials, with bonding agents, the bricks are made under high pressure and other steps of heat treatment process.

we can provided other kinds of brick too.
