Product Description
Magnesium oxide (chemical formula :MgO) is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in nature in the form of magnesite and is a raw material for magnesium smelting.
Fine white powder. No smell. Because of the different preparation methods, there are light and heavy quality. Strong refraction in the visible and near ultraviolet range. Exposed to the air, it is easy to absorb water and carbon dioxide and gradually become basic magnesium carbonate, light and heavy faster, combined with water to produce magnesium hydroxide, a slightly alkaline reaction, and the pH of saturated aqueous solution is 10.3. However, it is highly soluble in dilute acids and very slightly soluble in pure water, and its solubility is increased by the presence of carbon dioxide. Insoluble in ethanol. Relative density (d254)3.58. Melting point 2852ºC. Boiling point 3600ºC.

Application.
One of the main uses of magnesium oxide is the use of flame retardants, traditional flame retardant materials, widely used halogen-containing polymers or halogen-containing flame retardants combination of flame retardant mixture. However, once a fire occurs, due to thermal decomposition and combustion, it will produce a large amount of smoke and toxic corrosive gases, which will hinder fire fighting and personnel evacuation, corrosion of instruments and equipment. In particular, it has been found that more than 80% of the deaths in the fire are caused by the smoke and toxic gases produced by the material, so in addition to the flame retardant efficiency, low smoke and low toxicity are also essential indicators of flame retardants. The development of China's flame retardant industry is extremely unbalanced, and the proportion ofchlorine flame retardants is relatively heavy, which is the first of all flame retardants, of which chlorinated paraffin occupies a monopoly position. However,chlorineflame retardants release toxic gases when they act, which is far from the non-toxic and efficient pursuit of 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.
