Chemical Composition And Application Of Dolomite

Dolomite bricks are refractory materials made of calcined dolomite sand. It usually contains more than 40% CaO and 35% MgO. It also contains a small amount of impurities such as SiO 2, AlO 3 and FeO 3. The CaO/MgO ratio of natural dolomite fluctuates greatly. If the CaO/MgO ratio of brick is less than 1.39, it is called magnesia dolomite brick.
