  Magnesium oxide is divided into light and heavy magnesium oxide, heavy magnesium oxide is divided into light burning and heavy burning. Magnesite building materials are used in heavy magnesium oxide inside light burning, the so-called light burning and heavy burning is mainly different from the sintering temperature, when the sintering temperature is below 1200 degrees, generally speaking, the output of magnesium oxide is light burning magnesium oxide, when the sintering temperature reaches 1200 degrees above the firing of magnesium oxide is called heavy burning magnesium.

Magnesium oxide is generally referred to as heavy magnesium oxide, alias lamp powder. White or beige powder. It is easy to absorb moisture and carbon dioxide when exposed to air, and easy to gel and harden when mixed with magnesium chloride solution.

  Heavy magnesium oxide is directly calcined from magnesite and hydromagnesite. Properties of heavy magnesium oxide: white or beige powder, insoluble in water and ethanol, in the air can gradually absorb carbon dioxide and water to form magnesium carbonate double salt. It can be partially hydrated in hot water to form magnesium hydroxide. Heavy magnesium oxide and magnesium chloride solution stirring, easy cementing, hardening, magnesium oxide cement. The activity of heavy magnesium oxide varies greatly with the different production conditions. Between 800 and 900. Magnesium oxide produced under C has greater activity.

  Heavy and light burning magnesium oxide is used in rice milling industry for firing powder and half drum; The construction industry is used to manufacture artificial chemical floor, artificial marble, heat protection board, sound insulation board; Used as filling material in plastic industry; It can also be used to produce other magnesium salts. It is used as magnesium fertilizer in agriculture; For water treatment and desulfurization.

The principle of magnesium oxide used in sewage treatment: when magnesium oxide reacts with sewage to generate magnesium hydroxide, the harmful substances such as silicon in sewage react and dispose of them. Because magnesium hydroxide has the characteristics of buffer, activity, adsorption capacity, non-corrosive, safe and harmless, it has been widely used in water treatment system in recent years. In particular, the heavy metals in sewage are not easy to be metabolized in the environment, easy to be bioenriched and expanded step by step along the biological chain. The harm to the environment is more serious. Magnesium hydroxide has a large surface area, strong adsorption capacity and larger solubility product than general metals. Precipitates are also produced by displacement.

• One of the main uses of magnesium oxide is the use of flame retardant, traditional flame retardant materials, widely used halogen-containing polymers or halogen-containing flame retardant mixtures

  Magnesium oxide is widely used in the construction industry for waterproof, moisture-proof, heat insulation, sound insulation and other aspects of all kinds of buildings, such as fireproof coating and foundation treatment. Magnesium oxide is a kind of polymer material, which has good heat resistance and abrasion resistance. Because it has good corrosion resistance and heat preservation performance. In the construction industry, it can produce special cement and insulation board containing magnesium.

  Magnesium oxide is found in a wide range of applications, which include manufacturing in the fields of power, electronics, and chemicals. It is an inorganic substance with high fire resistance and insulation performance. The volume of light magnesium oxide is loose and white solid. Magnesium oxide ions decompose to produce a lot of heat and oxygen, thus forming a new solid. Fire resistance and heat resistance are very good, not easy to melt at high temperature, so magnesium oxide has a strong fire resistance. Act as polishing agent in the steel ball polishing industry; Dye industry as aminophenol production excipients; Electrical industry as a raw material for phenolic resin.
