What is Aluminum oxide? Aluminum oxide Al2O3 is an organic substance. This is a hard compound that has a melting and boiling point of 2960degC. It is a crystalline ion that can be ionized under high temperatures.
Aluminum oxide, also known as aluminum oxide, is a white solid, which is not soluble in any liquid, has a neutral odor, tastes and smells, and it’s extremely hard. It is easy for it to absorb water, but not deliquescence. Aluminum oxide is amphoteric oxide, a type of oxide that is easy to absorb moisture but does not deliquescence (after burning, it will not absorb moisture).
Application of Nano Aluminum Oxide
Lithium separator coating material
The high-purity Nano-Aluminum dioxide is used to coat the positive and the negative electrode separators. This coating can be used to improve heat resistance, resistance to high-temperature, and insulation. This will prevent the battery from overheating due to temperature. The battery is melted and short-circuited.
Lithium cathode additives for batteries:
High-purity Nano-Aluminum doped by lithium cobalt, lithium manganate etc. Improve thermal stability, cycle performance, overcharge resistance and inhibit oxygen generation. Reduce the electrochemical loss of specific capacity, increasing the specific capacity LiCoO2.
Catalyst Carrier:
High-purity g-type Nano- Aluminum oxide This porous material has a surface area per gram of hundreds of square metres, is highly active, and has a strong adsorption ability. It is widely used in the petroleum refinery and petrochemical industries as an adsorbent. It has the same drying capacity as phosphorus hexoxide. It can be used again after heating to 175degC at least 6-8 hours.

Anti-caking powder coating
Powder coatings are made with nano aluminum oxide, which has an anti-caking and bulking effect. Nano-Aluminum can be used to prevent powder from agglomerating during summer. It also has excellent storage properties, especially for powders in environments with high temperatures and high humidity.
Wear-resistant Hardener for Coatings, Rubber, and Plastics
By adding Nano-Aluminum, oxide to the coating, it can significantly improve its scratch and wear resistance. This is up to five times better than traditional coatings. Nano-Aluminum dioxide can be added to paints in order to form a uniform, very hard, fine network structure on the surface. This protects the polymer paint below the nano-aluminum oxide layer. Nano paint has a better anti-scratch than the original. The paint was increased by three times and is widely applied in automotive paints. The hardness of coatings can be significantly increased by adding nano aluminum oxide. By adding 20%, the coating can reach 6-7H. The coating’s transparency is not affected.
Thermal conductivity (thermal conductivity) of adhesives, coatings, plastics and rubbers
Nano-scale Aluminum Oxide has a high thermal conduction and has a large amount spherical filling. Surface treatment agents like coupling agents can be used to improve the compatibility between the matrix resin and the filler. They also improve the thermal conduction of the matrix without reducing mechanical properties.
Ceramics:
Nano Aluminum oxide is high in purity, has uniform particle sizes, and has good dispersibility. Addition of VKL30 at a rate of 10% to sintered ceramics increases the molding pressure. It also reduces the number of pores. This results in a higher density ceramic green body.
Powder metals:
Nano Aluminum for metallurgy with small particles, large surface area, high activities, adding 1-3% Nano Aluminum to prevent densification, enlargement of crystal grain, increased hardness, enhanced conductivity and mechanical property, as well as an increase in melting point, and high temperature resistance.
Polishing:
Aluminum oxide particles are uniform and have a high spherical form. It is also a great material for metallographic polishing. It is suitable for a variety of applications including stainless steel mirror, titanium, cast-iron, aluminum mirror, stone mirror, paint polishing and resin polishing.
