Dead Burnt Magnesia (DBM) is a calcium rich high-temperature refractory material in form of granules, processed from natural crypto crystalline magnesite ore and sintered at high temperature (called calcination or dead burning) and consisting of magnesium oxide (MgO) and Calcium oxide (CaO).

*Note: Dead Burnt Magnesia (DBM) has the highest melting point of all common refractory oxides.

The properties of heat resistance and chemical stability make Dead Burnt Magnesia valuable in industries requiring refractory materials capable of withstanding severe thermal conditions while maintaining structural integrity and performance over time.

1. Furnaces: DBM is extensively used in steelmaking processes, such as Electric Arc Furnaces (EAFs) and Basic Oxygen Furnaces (BOFs). It serves as a refractory lining due to its ability to withstand high temperatures and resist thermal shock, making it ideal for containing molten metal and protecting furnace walls from heat and chemical corrosion.

2. Ladles and Secondary Refining Vessels: DBM refractories are used in ladles and secondary refining vessels in the steel industry. These vessels handle molten metal and slag at extremely high temperatures.
