Magnesium oxide MgO CAS 1309-48-4

Overview of magnesium oxide MgO:

Magnesium oxide  MgO is an alkaline oxide,which has the same properties as alkaline oxides,and is a gelling material.It is white or off-white powder,odorless, tasteless, and non-toxic.It is a typical alkaline earth metal oxide with the chemical formula MgO.The melting point is 2852°C,the boiling point is 3600°C,and the density is 3.58g/cm3(25°C).Soluble in acid and ammonium salt solution,insoluble in alcohol.The solubility in water is 0.00062 g/100 mL(0 °C)and 0.0086 g/100 mL(30 °C).When exposed to the air,it easily absorbs water and carbon dioxide and gradually becomes basic magnesium carbonate.Light products are faster than heavy products.It combines with water to form magnesium hydroxide under certain conditions, which shows a slightly alkaline reaction.The pH of a saturated aqueous solution Is 10.3.It is soluble in acid and ammonium salt and hardly soluble in water, and its solution is alkaline.Insoluble in ethanol. It has strong refraction in the visible and near ultraviolet range. Magnesite(MgCO3),dolomite(MgCO3•CaCO3)and sea water are the main raw materials for the production of magnesium oxide.Thermal decomposition of magnesite or dolomite obtains magnesium oxide.Treat seawater with slaked lime to get magnesium hydroxide precipitation,and burn magnesium hydroxide to get magnesium oxide.It is also possible to use the magnesium chloride halide obtained in the comprehensive utilization of seawater or the brine after bromine extraction as raw materials,add sodium hydroxide or sodium carbonate,etc. to produce magnesium hydroxide or basic magnesium carbonate precipitation, and then burn to obtain magnesium oxide.China mainly uses magnesite,dolomite, brine or brine as raw materials.

Application of magnesium oxide MgO:

What are the applicable scopes of magnesium oxide MgO powder?

 Magnesium oxide MgO is to determine sulfur and pyrite in coal and sulfur and arsenic in steel. Used as a standard for white pigments.Light magnesium oxide is mainly used as a raw material for preparing ceramics, enamels,refractory crucibles and refractory bricks.It is also used as a polishing agent,adhesive, coating,and paper filler,as an accelerator and activator for neoprene and fluorine rubber.After mixing with magnesium chloride and other solutions,it can be made into magnesium oxide water solution.Used in medicine as an antacid and laxative,for hyperacidity of the stomach and duodenal ulcer.Used as a catalyst in the chemical industry and as a raw material for the manufacture of magnesium salts. magnesium oxide MgO also used in the manufacture of glass, dyed meal,phenolic plastic,etc. Heavy magnesia is used in the rice milling industry for firing,grinding and half-rolling.The construction industry is used in the manufacture of artificial chemical floors,artificial marble heat-proof panels and sound-proof panels,and as fillers in the plastic industry.It can also be used to produce other magnesium salts.

One of the main uses of magnesium oxide is as a flame retardant.Traditional flame retardant materials are widely used in flame retardant mixtures composed of halogen-containing polymers or halogen-containing flame retardants.However, once a fire occurs, due to thermal decomposition and combustion,a large amount of smoke and toxic corrosive gases will be generated,which will hinder fire fighting and personnel evacuation,and corrode equipment and equipment. In particular, people have found that more than 80% of fatalities in fires are caused by dense smoke and toxic gases produced by materials.Therefore, in addition to flame retardant efficiency, low smoke and low toxicity are also indispensable indicators for flame retardants.The development of China's flame retardant industry is extremely unbalanced.The proportion of chlorinated flame retardants is relatively large,ranking first among flame retardants,among which chlorinated paraffins occupy a monopoly position. However,chlorine-based flame retardants release toxic gases when they act,which is a long way from the non-toxic and high-efficiency pursued by modern life. Therefore,in order to comply with the development trend of low smoke,low toxicity and pollution-free flame retardants in the world, the development, production and application of magnesium oxide flame retardants are imperative.
