High refractoriness, high basic slag resistance and good thermal conductivity. lower porosity,used in furnace.
Magnesia Brick
The bricks have the characteristic of high refractoriness, high basic slag resistance and good thermal conductivity. lower porosity, smaller diameters of the porosity.
Magnesia bricks are mainly used in basic open furnace, holding furnace and the bottom and side-wall of electric, bottom of heating furnace, inner of alkaline-making furnace in paper making factory and etc.
