Dead Burned Magnesia Physical Property
The Molecular Formula of Magnesium Oxide: MgO
Molecular weight: 40.30 (international standard)
Messi Magnesium oxide is produced from magnesite and ammonium bicarbonate by carbonization and calcination process. We have self-produced mining raw materials and semi-finished products testing means, with mature and stable production lines. The product quality is stable, and the performance is good. It can meet the needs of customers in different industries.
This product is used for fluorine rubber, butyl rubber, cable, conveyor belt, adhesive, FRP and other products.
Most of the magnesium oxide is processed into Dead Burned Magnesia (DBM), also called sintered magnesia.
Refractory Application of Magnesium Oxide
Refractory materials maintain physical and chemical stability at high temperatures. Dead-burned magnesium oxide, which is produced in shaft and rotary kilns at temperatures over 1500℃, has reduced chemical reactivity and therefore is suited to refractory applications.
Magnesium oxide (MgO) has a very high melting point of 2800 degrees ℃. High melting point, along with resistance to basic slags, wide availability, and moderate cost makes magnesium oxide (MgO) the choice for heat intensive metal, glass, and fired-ceramic applications.
By far the largest consumer of magnesium oxide (MgO) worldwide is the refractory industry. Monolithic gunnables, rammables, castables, spinel formulations, and magnesia carbon based refractory bricks, all formulated using magnesium oxide (MgO), are widely used for basic steel refractory linings. These products are also used in ferroalloy, non-ferrous, glass and ceramic kiln applications.
