The Molecular Formula of Magnesium Oxide: MgO
Molecular weight: 40.30 (international standard)
Appearance: White powder
Reactive 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.
Is magnesium oxide highly reactive?
The speed at which this dissociation occurs is the main technical characteristic of MgO that is of interest to the tanner. If the dissociation is rapid, the MgO is considered highly reactive, if the dissociation is slow, it will be of low reactivity. For traditional chrome tanning, low magnesium oxide reactivity is the most widely used. The reactivity of MgO is a result of three factors: chemical composition (purity), particle size distribution, and
surface area. Each of these parameters will be discussed in detail.
Magnesium oxide for industrial use is obtained from two main sources: mineral (mines) and water (sea, salt lakes, groundwater salines, etc). Depending on its origin, treatment of the oxide can vary, but the final features are defined by the same operations regardless of the origin. This means that the reactivity of MgO does not depend on the source of production, but from the operations used in refining the product.
Caustic Calcined Magnesia (CCM) is a highly reactive form of magnesium oxide produced by calcining or burning crude magnesite at relatively low temperatures (>1000 °C). Applications for caustic calcined magnesia include water treatment and in production of feed stock, fertilizers, and some cosmetics.
