  Appliion Of Dolomite In Refractory Industry

  1. Dolomite Brick. Dolomite bricks are made of dolomite sand that is calcined from natural dolomite. Dolomite brick contains w (CaO) ≥ 40%, w (MgO) ≥ 35%, and also contains a small amount of SiO2, Al2O3, Fe2O3 and other impurities. If the mass ratio of CaO to MgO in the brick is less than, it is called magnesia dolomite brick.
