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, hard solid. It is not soluble in any liquid, has no taste or odor, and does not absorb moisture. It is a white solid that absorbs water easily, 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).
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 ceramic coating can be used to improve heat resistance, resistance to high-temperatures, 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, a high level of 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 that of pentoxide phosphorus. After usage, it can also be regenerated by heating to 175degC and using for 6-8h.

Powder coatings that are resistant to caking
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 temperature and 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 paint surface. This protects the polymer paint below the layer from damage. Nano paint has better scratch resistance than original paint. Its hardness is increased three-fold and it is widely used for automobile paints. Adding nano aluminum oxide to the coating can increase its hardness by a significant amount. A 20% addition can bring the coating up to 6-7H. The coating’s transparency is not affected.
Thermal conductivity (thermal conductivity) of adhesives, coatings, rubbers and plastics
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 affecting its 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 up to 3% Nano Aluminum to increase hardness and conductivity.
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 polishing and cast iron polishing.
