Dead burnt Magnesia
Re-burned magnesia is made of natural magnesite and calcined in high temperature shaft kiln. It is the raw material for making bricks and producing unshaped refractories, and the finished products are used for steel making, electric furnace bottom and ramming furnace lining.

Dead Burnt Magnesite (DBM) Bricks made with Dead Burnt Magnesite or Magnesia (DBM) are an important category of basic refractoriness as it has the highest melting point i.e. 28000C, among all basic refractoriness. Magnetite bricks are characterized by good resistance to basic slag as well as low vulnerability to attack by iron oxide and alkalis. They are widely used in applications such as glass tank checkers, as sub hearth brick for electric arc furnaces and as back up lining in basic oxygen furnaces. Magnetite compositions are also widely used in ladle slide gate & gas purging refractories. Magnesite in combination with chrome, spinel and carbon is also used for various applications.
