What is Aluminum oxide? Aluminum oxide Al2O3 is a chemical compound that has an inorganic formula. This is a hard compound that has a melting and boiling point of 2960degC. It is an ionic crystalline material that can ionize at high temperatures.
Aluminum oxide, also known as aluminum oxide, is a white solid, which is not soluble in any liquid, has no taste or odor, and it’s extremely hard. It is easily absorbed moisture, but it doesn’t 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).
Nano Aluminum Oxide
Lithium separator coating material
The high-purity Nano-Aluminum dioxide is applied as a ceramic layer to the positive/negative electrode separators. It plays a role in the heat resistance, the high-temperature-resistance, and the insulation. These properties can prevent the battery from overheating due to high temperature. The battery is melted and short-circuited.
Lithium cathode materials additives
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, high activity and a strong adsorption ability. It is widely used in the petroleum refinery and petrochemical industries as an adsorbent. Its drying capability is equal to phosphorus pentoxide. After usage, it can also be regenerated by heating to 175degC and using for 6-8hrs.

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
The wear resistance can be improved by up to five times with the addition of Nano-Aluminum. 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’s anti-scratch properties are better than original. The paint was increased by three times and is widely applied in automobile paints. Nano aluminum oxide increases the hardness of coatings. By adding 20%, the coating can reach 6-7H. The coating’s transparency is not affected.
Thermal conductivity (thermal conductivity) of adhesives, coatings, rubbers and plastics
Aluminum oxide nano-scale has a thermal resistance of 30. It also has a large amount spherical material. 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.
Nano Aluminum oxide is high in purity, has uniform particle sizes, and is easily dispersed. 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. Small particle size, high specific surface area. Add 1-3% Nano Aluminum to the matrix to avoid densification, enlargement of crystal grain, increased hardness and conductivity.
Aluminum oxide particles are uniform and have a spherical, high-quality shape. It is also a great material for metallographic polishing. It can be used to polish optical glass, stainless steel, optic glass, spectacle lenses, resin lens, zinc, or germanium.
