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 absorbs water easily, but it doesn’t deliquescence. Aluminum oxide is amphoteric oxide, soluble and resistant to corrosion in both acidic and alkaline solutions.
Application of 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. This 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 materials additives
High-purity Nano-Aluminum doped by lithium manganate or cobalt oxide. 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 adsorbents, catalysts, and catalyst carriers in the petroleum and petrochemical industries. It also serves as a deacidification for transformer and turbine oils in industry. It has a drying capacity that is equal to phosphorus pentoxide. 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 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 surface. This will protect the polymer paint below the layer from damage. Nano paint offers better scratch resistance than original paint. It has been enhanced by 3 times, and 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.
Thermoconductivity of adhesives, coatings, and rubbers.
Aluminum oxide nano-scale has high thermal conduction and large spheres of filling. Surface treatment agents like coupling agents can be used to improve the compatibility between the resin and filler as well as the thermal properties of the matrix without reducing their 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. Adding 1-3% Nano Aluminum to the matrix will prevent densification, enlargement of crystal grain, increased hardness and conductivity. Mechanical properties and melting point are also improved.
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 polishing and cast iron polishing.
