Dead Burned Magnesium Oxide (DBM) for Refractory Applications

Dead Burned Magnesium Oxide (DBM) for Refractory Applications

Refractory materials maintain physical and chemical stability at high temperatures. Dead burned magnesium oxide (DBM), also known as Periclase, which is produced in shaft and rotary kilns at temperatures over 1500oC, has reduced chemical reactivity and therefore is suited to refractory applications.

Magnesium oxide (MgO) has a very high melting point of 2800oC. High melting point, along with resistance to basic slags, wide availability, and moderate cost makes dead burned magnesium oxide the choice for heat intensive metal, glass, and fired-ceramic applications.

By far, the largest consumer of magnesium oxide worldwide is the refractory industry. Monolithic gunnables, rammables, castables, spinel formulations, and magnesia carbon based refractory bricks, all formulated using dead burned magnesium oxide, are widely used for basic steel refractory linings. These products are also used in ferroalloy, non-ferrous, glass and ceramic kiln applications.

MagChem®P98 high purity dead burned magnesium oxide (MgO) is used in the manufacture of refractory brick, castables, and monolithic gunning mixes, for use in the steelmaking and other refractory applications.
