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 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 a white solid that absorbs water easily, but it doesn’t deliquescence. Aluminum oxide is amphoteric oxide, which is easy to absorb moisture but does not deliquescence (after burning, it will not absorb moisture). It is inert, corrosion resistant, slightly soluble, alkaline, and inorganic acid solutions.
Nano Aluminum Oxide
Lithium separator coating material
The high-purity Nano-Aluminum dioxide is used to coat the positive and the negative electrode separators in lithium batteries. These coatings are responsible for heat resistance, resistance to high-temperatures, and insulation. They can also prevent overheating of the power battery 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 and resistance to overcharge, inhibit oxygen formation and LiPF6 breakdown, and avoid contact between LiCo02 with electrolyte. 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 petrochemical and petroleum industry as a catalyst and adsorbent. It also acts as a deacidifier for transformer and turbine oils. Its drying capability is equal to that of pentoxide phosphorus. After usage, it can also be regenerated by heating to 175degC and using for 6-8 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
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 layer. Nano paint is 3 times more scratch resistant than original paint. It is widely used for 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 high thermal conduction and large spherical particles. 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 the 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, large surface, high activity. Add 1-3% Nano Aluminum to the metal matrix in order to avoid densification, enlargement of crystal grain, increased hardness and conductivity and mechanical properties.
Aluminum oxide particles are uniform and have a high-spherical profile. 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.
