This paper presents the ways of comprehensive utilization of the natural magnesium-containing resources and the trends of the MgO-based refractories used in high-temperature industries. In the first part, the uses and productions of metal Mg, sorel cement, Mg(OH)2 fire retardant, light magnesium carbonate, light magnesia and magnesium sulphate are described. In the second part, the developments of MgO-based refractories used in steelmaking process, nonferrous metallurgy, cement rotary kiln and waste melting furnace are described from some applied theories, including corrosion resistant and slaking resistant MgO-CaO materials, chrome-free bricks such as MgO-CaO-ZrO2, MgO-MgO Al2O3, MgO-MgO·Al2O3-ZrO2,MgO-MgO·Al2O3-2MgO·TiO2 and MgO-FeO·Al2O3, and MgO-containing monolithic refractories etc.
