What is Alumina Nanoparticle used for?

The coating material for the lithium battery's diaphragm is High purity micro alumina. It acts as an insulation and heat resistant coating.

Additional ingredients for lithium battery cathode materials:
Doped with lithium cobalt, lithium manganate, high-purity nanoalumina can increase thermal stability and cycle performance, prevent the formation of oxygen, the decomposition LiPF6, and reduce direct contact between LiCo02 (electrolyte) and LiCo02. It also increases the electrochemical specificity of LiCoO2.

A porous material with high purity of g type nano-alumina has a surface area of many hundred of meters per gram. It also exhibits high activity and strong absorption capabilities. It's a common adsorbent, catalyst, and carrier in the petroleum refining, petrochemical, and oil industry.

Powder coating Anti-caking:
Summer can be prevented by nano-alumina. The use of nanometer aluminum trioxide in powder coatings is a great way to improve powder coating fluffiness and provide good anti-caking effects. This powder coating is stable in extreme temperatures or high humidity environments.

Hardening and wear-resistant coating for rubber or plastics:
Nano-alumina can increase the durability and resistance to scratches of the coating by adding between 2 and 5 percent. The paint can have a fine network structure that protects the polymer paint from scratching and wear. The scratch resistance of nanopaint is three times better than original paint. This paint is commonly used for automobile paints, such as the GM-Aluminum Trioxide. A nano-aluminum triooxide is able to significantly increase the coating's hardness, with about 20% reaching 6-7H. It does not affect the transparency of coating.

Plastics, rubber, adhesives, paint thermal conductivity:
One crystal Alumina thermal conductivity (30 nanometer alumina), high thermal conductivity, large-spherical filling. Surface treatment agents like coupling agents can be used to improve thermal conductivity. They are often used in order to improve compatibility with resin matrix fillers and other matrix materials.

High purity and uniform size of the nano-alumina particles make it a great choice for dispersing. If 10% alumina are added to sintered ceramics it can increase the forming pressure, which reduces the number pores and increases the density of ceramic blanks. It also improves the mechanical and density properties of sintered alumina ceramics and lowers the sintering temperatures.

The nano alumina used in metallurgy is small in size with a high specific surface area.

These alumina particles have uniform sphericity and can be used for polishing. Polishing zinc is fast, bright, and without scratches.
