                MGO magnesium oxide

MGO Magnesium oxide is an oxide of magnesium, an ionic compound. At room temperature is a white solid. Magnesium oxide in the form of magnesia in the nature, is the rule of magnesium raw materials.

MGO Magnesium oxide has a high degree of fire insulation properties. By 1000 ℃ above the high temperature burning can be transformed into crystal, rose to 1500 - 2000 ° C  was dead burned magnesium oxide (that is, said magnesia) or 

sintered magnesia.

MGO magnesium oxide commonly known as bitter, also known as magnesium oxide, MGO magnesium oxide is alkaline oxide, with alkaline oxide of the nature, are cementitious materials. MGO Magnesium oxide is a white powder (light yellow for the magnesium nitride), odorless, tasteless, non-toxic, is a typical alkaline earth metal oxide, chemical formula MgO. White powder, melting point of 2852 ° C, the boiling point of 3600 ° C, the relative density of 3.58 (25 ° C). Soluble in acid and ammonium salt solution, insoluble in alcohol. Solubility in water is 0.00062 g / 100 mL (0 ° C) 

0.0086 g / 100 mL (30 ° C). Exposed to the air, easy to absorb moisture and carbon dioxide and gradually become the basic magnesium carbonate, light goods heavier goods faster, combined with water under certain conditions to produce magnesium hydroxide, was slightly alkaline reaction, 

saturated aqueous solution pH Is 10.3. MGO Magnesium oxide soluble in acid and ammonium salts are insoluble in water, the solution is alkaline. Insoluble in ethanol. In the visible MGO magnesium oxide and near ultraviolet light within the range of strong refraction. Magnesite (MgCO3), dolomite (MgCO3 · CaCO3) and seawater are the main raw materials for the production of MGO magnesium oxide. Thermal decomposition of magnesite or dolomite MGO magnesium oxide. With the use of lime to deal with seawater magnesium hydroxide precipitation, burning magnesium hydroxide was 

magnesium oxide. MGO magnesium oxide can also be used in the comprehensive utilization of magnesium chloride brine or bromine brine as raw material, add sodium hydroxide or sodium carbonate and other magnesium hydroxide or alkaline magnesium carbonate precipitation, and then burned magnesium oxide. Now MGO magnesium oxide is mainly used in China to magnesite, dolomite, brine or halogen as raw material.
