Nanometer magnesium oxide is a new type of nanoparticle material with a white appearance, high purity, large specific surface area, and composed of very fine grains with good dispersion and relative density of about 3.58 (25℃).
Melting point 2852℃, boiling point 3600℃. Insoluble in water.
Nanoscale magnesium oxide has obvious small size effect, surface effect, quantum size effect and macroscopic tunneling effect. After modified treatment, there is no agglomeration phenomenon. It has many specific functions and important application value in optical, catalytic, magnetic, mechanical, chemical and other aspects.

Application characteristics in lithium batteries:
1. Application in lithium battery
By adding an appropriate amount of nanometer magnesium oxide to the anode material of lithium ion battery, the anode material obtained has a reversible discharge capacity greater than 140mAh/g and good cycling performance.
Use in positive electrode materials can improve the conductivity, recommended additions of 0.3-0.5%.
2. Application of zinc-Nickel battery
The addition of magnesium oxide to the zinc negative active substance by physical mixing method can reduce the polarization of charge and discharge, reduce the internal resistance in the late cycle, improve the utilization ratio of the negative plate active substance, and extend the cycle life of the battery. The appropriate addition amount of magnesium oxide is 1.0%wt, and the addition amount should not exceed 2.0%.
Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.
