Application of nano alumina powder in various fields

Coating material for lithium battery diaphragm


high-purity nano-alumina

The ceramic coating is applied to the negative and positive electrode separators of the lithium batteries. It acts as insulation, heat resistance, and high temperature resistance to keep the battery safe from damage. The battery is melted and then short-circuited.

Additives to the lithium battery cathode materials

Doping high purity nano-alumina to make lithium cobaltate, LiMnA, and other lithium-containing compounds. It can increase thermal stability, enhance cycle performance and resist overcharge, inhibit the generation of oxygen, and avoid LiCo02. Direct contact with an electrolyte reduces electrochemical specific capacit, which allows for increased electrochemical specificity of LiCoO2.

Catalyst Carrier

The porous high-purity, g-type, nano-alumina has an internal area of hundreds upon hundreds of square metres per gram. It is also highly active and has strong adsorption capabilities. It is an important adsorbent, catalyst, and catalyst carrier in the petroleum refining, petrochemical, and oil industry.

Powder coating Anti-caking

The nano aluminum oxide is used to enhance the bulkiness of powder coats. It also has an anti-caking effect. Powder coatings in high-temperature and high humidity environments will have good storage properties.

Add 5-20% nano-alumina powder to your coating. The coating’s wear resistance and scratch resistance will be 22 better than the conventional coating. 5 times. Nano-alumina can be used to create a very fine network structure on the paint surface that protects the polymer paint layers from damage. The nano-paint’s anti-scratch properties are superior to the original. The paint’s strength is tripled and it is widely used in paint for cars and other purposes. The coating can be made harder by adding nano-alumina. A 20% increase can bring it to 6-7H. This does not affect the coating’s transparency.

Thermo conductivity: Plastics, rubbers. Adhesives, coatings.

The thermal conductivity of alumina single crystal is 30, with a high thermal conductivity and large spherical-filling. Coupling agents, which are surface treatment agents that improve thermal conductivity and compatibility between the resin matrix matrix and the filler, are often used.


: Nano Alumina is high purity, uniform in particle size, and has good dispersibility. By adding about 10% of sintered clays, you can increase the molding pressure, reduce the number pores, and improve the mechanical and density properties of alumina ceramics following sintering.

Powder metallurgy

For metallurgy: Nano-alumina powder, small particle sizes, large specific area, high activity. Add 1-3% of nanoalumina to prevent matrix density and grain size increases. This will enhance hardness, electrical conductivity, mechanical properties, and enhanced melting point.


Alumina has uniform particles with high sphericity. It is an excellent material for precision polishing and metallographic polishing. It is suitable for stainless-steel mirror polishing and titanium metal polishing. Paint polishing. Resin polishing. Glass polishing.
