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, LiMnate, and other lithium-containing compounds. It can increase thermal stability, enhance cycle performance, and resist overcharge, as well as inhibiting the generation of oxygen, and the decomposition LiPF6.

Catalyst Carrier

High-purity, g-type, nano-alumina has a porous structure with a high level of activity and a high adsorption ability. It is an important adsorbent, catalyst, and catalyst carrier in the petroleum refining, petrochemical, and oil industry.

Anti-caking powder coating

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

Add 5-20% of nanoalumina powder to your coating. The coating will be 22 more scratch-resistant than a traditional one. 5 times. Nano-alumina can be used to create a network structure on the paint’s 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 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 to your mold, you can increase the molding pressure, reduce the number pores, and improve the density and mechanical properties after 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 is very uniform and has 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.
