Al2O3 is an inorganic compound with the chemical Formula Al2O3. This is a hard compound that has a melting and boiling point of 2960degC. It is a crystalline ionic compound 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 easy for it to absorb water, but not 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, slightly soluble, resistant to corrosion, and soluble only in inorganic acid and alkaline solution.
Application of Nano Aluminum Oxide
Lithium separator coating material
The high-purity Nano-Aluminum dioxide is used to coat the positive and negative 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 manganate or cobalt oxide. Improve thermal stability, cycle performance, overcharge resistance and inhibit oxygen generation. Reduce the electrochemical loss of specific capacity, increasing the specific capacity LiCoO2.
High-purity g-type Nano-
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 petrochemicals and the petroleum industry as a catalyst and catalyst carrier, and also in transformer oil and turbine oils. Its drying capability is equal to that of pentoxide phosphorus. It can be used again after 6-8 hours of heating to 175degC.
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 paint surface. This protects the polymer paint below the layer from damage. Nano paint’s anti-scratch properties are better than the original. The paint was increased by three times and is widely applied in automobile 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 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.
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.
