According to the survey, Chinese mainland has a large number of magnesium resources, and its total reserves rank first in the world. Magnesium oxide is widely used in electric cable, rubber products, medicine, adhesives, metallurgy, ceramics and other industries. With the industrial development and upgrading and the need and development of new high-tech functional material market, a variety of innovative and refined magnesium oxide products have been developed, mainly used for high-grade lubricating oil, high-grade tanning alkali extraction grade, medical and pharmaceutical industry, food grade. Nearly 10 kinds of composition, such as silicon steel grade, high-grade electromagnetic grade and high-purity magnesium oxide.

Although Magnesium Oxide is an auxiliary material, its application and influence in different industries are very great. Influence in the electric cable industry: the influence of vulcanization accelerator, coke inhibitor, filler, acid absorbent, fire and flame retardant, heat resistance, corrosion resistance and wear resistance; the influence in the adhesive industry: the influence of vulcanization accelerator, coke inhibitor and acid absorbent, accelerating reaction in the resin reaction liquid. Therefore, it can be seen that many products add magnesium oxide, which is just like that you need to put monosodium glutamate in the daily cooking, without adding taste, and put a little of this dish will be beautiful in color, fragrance and taste.
In recent years, with the development of technology, new functional materials have become a hot topic of scientific research, and the quality level of raw materials of new functional materials has become a yardstick of the development of new functional materials. At present, it mainly develops the application in the new functional materials of luminescence, electronic optics, electronic and other industries. The new functional materials mentioned above have very strict regulations on the purity of raw materials.

Although there are no general standards and specifications in the world at this stage, except for reference to the application regulations of new functional materials, the chemical material standard will be used as the reference standard. Taking high-purity electronic grade basic magnesium carbonate and magnesium oxide as examples, they are mainly used for aerospace electronic components, military electronic components, communication equipment, radar, etc., so the technical specifications of high-purity electronic grade basic magnesium carbonate and magnesium oxide are determined.
One of the main uses of MgO is as a fire retardant. The traditional fire-proof materials widely choose the combination of halogen-containing polymer or halogen-containing fire-proof agent. In case of fire accident, there will be too much smoke and toxic and harmful corrosive gas due to combustion and thermal decomposition, which will corrode instruments and equipment, thus preventing fire fighting and crowd evacuation. According to data statistics, 80% of the above casualties in fire accidents are caused by smoke and harmful gases caused by materials. Therefore, in addition to the efficiency of fire protection, low smoke becomes a standard that fire retardant cannot lack.
