How About the AR Magnesium Oxide?

Name：AR Magnesium Oxide

   The AR magnesium oxide is a kind of white and shapeless powder, and colorless, tasteless, non-toxic. The relative density is from 3.26 to 3.43. It is soluble in acids and ammonium salt solution, insoluble in water and ethyl alcohol. On the scale of near ultraviolet light and visible ultraviolet light,it has strong refractivity. When it is exposed to the air, it is easy to pick up moisture and carbon dioxide. And then, it gradually becomes basic magnesium carbonate, and forms magnesium hydrate integrates with water and presents alkalescency reaction. The PH value of the saturated water solution is 10.3. However, it is easy to soluble in dilute acid, and slightly soluble in pure water. The existing of carbon dioxide increases the solubility. It is a kind of soft catalyst. The density ratio is 3.58, melting point is 2852℃ and boiling point is 3600℃.

Chemical Formula: MgO

Relative Molecular mass: 40.30

Quality Standard: HG/T2679-2006

Ionic Equation:

MgO+2H+=Mg2++H2O

MgO+2NH4+=Mg2++2NH3↑+H2O

Main Application

The AR magnesium oxide mainly used for reagent industry, other chemical engineering or midbody. The fluorescent grade magnesium oxide mainly used for tribasic fluorescent powder and the raw materials of other luminous bodies.

Preparation Method

Vapor phase method, The brine - ammonium bicorbonate method, Carbonization method

The matters need attention and safety precautions

Respiratory protection: Recommend wearing anti-dust respirator.

Eye protection: In necessity, it can adopt safety face shield.

Protection suit: Wear work clothes with tight sleeves.

Hands protection: Must wear the protective gloves.

Invasion route: inhalation, ingestion.

Health hazard: It causes the magnesium foundryman's fever if inhaled. The symptoms include metallic taste in mouth, thirst, dry throat, inappetence, chest can feel tight, dry cough, headache, swirl, limb pain and feel cold with a high temperature. A large number of magnesium oxide dust may block the sebaceous gland duct and lead the skin papules, eczema.

Method of extinguishing: non-combustible. And the available fire fighting medium around the fire.

Others: At the work site, No Smoking, eating and drinking. After work, changes clothes after showering. Pay attention to cleanliness and personal hygiene.

   As the one of magnesium oxide manufacturers engaged in the earlier, the president of Meishen Technology introduces, “The technical innovation is the sources of all things.” Depending on the technological superiority, Meishen Technology increases the investment of research and development in recent years, and forms several kinds of product line. These products include light magnesium oxide, food grade magnesium oxide, AR magnesium oxide, pharmaceutical grade magnesium oxide and so on. What’s more, it develops and researches a group of new magnesium compound with proprietary intellectual property rights.
