Properties and Application of Magnesium Oxide by Medium-grade Magnesia Manufacturers

Date:2017-07-25 author: click:

Chemical equation of magnesium oxide:

MgCl2(melting)= Mg+Cl2(electrolysis)

MgO+C = Mg+CO(high temperature)

White or light yellow powder, odorless, tasteless, non-toxic, insoluble in water or ethanol, slightly soluble in ethylene glycol, melting point 2852 C, boiling point 3600 C, magnesium oxide has a high fire-resistant insulation performance. It can be transformed into crystals by high temperature burning above 1000 C, and sintered magnesia or magnesia by dead burning up to 1500 C.

Medium-grade magnesia manufacturer introduces its chemical properties:

Magnesium oxide is an alkaline oxide in magnesia factories. It has the generality of alkaline oxide. It belongs to cementitious material. It is insoluble in acid and ammonium salts but insoluble in water. Its solution is alkaline. It is insoluble in ethanol. It reacts slowly with water and produces magnesium hydroxide with strong refractive properties in the visible and near ultraviolet light range.

Medium grade magnesia

Magnesium oxide classification:

It can be divided into light magnesium oxide and heavy magnesium oxide. Light weight, loose volume, white amorphous powder. It is odorless, odorless and non-toxic. The density was 3.58g/cm3. It is insoluble in pure water and organic solvents, and its solubility in water increases with the presence of carbon dioxide. It can dissolve in acid and ammonium salt solution. It is transformed into crystals by high temperature burning. When exposed to carbon dioxide in the air, magnesium carbonate compound is formed. Heavy compact, white or beige powder. It is easy to combine with water and absorb water and carbon dioxide in exposed air. It is easy to gel and harden when mixed with magnesium chloride solution.

With the upgrade of industrialization and the demand and development of high-tech functional materials market, a series of high-tech and fine magnesia products have been developed and produced, which are mainly used for nearly ten varieties, such as high-grade lubricants, high-grade tanning alkali extraction, food-grade, medicine, silicon steel grade, high-grade electromagnetic grade and high-purity magnesium oxide.
