What is Aluminum Oxide
Aluminum oxide
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 be heated to 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, slightly soluble, resistant to corrosion, and soluble only in alkaline or inorganic acid solutions.
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 applied as a coating on the lithium battery to improve heat resistance, resistance to high-temperatures, and insulation. This will prevent the power batteries 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 adsorbents, catalysts, and catalyst carriers in the petroleum and petrochemical industries. It also serves as a deacidification catalyst for transformer and turbine oil. 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 humidity and temperature.
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 form an extremely fine, uniform, hard and durable network structure on the paint surface to protect the polymer coating below. Nano paint is 3 times more scratch resistant than original paint. It is widely used for automobile paints. Addition of Nano aluminum oxide to the coating can increase its hardness by up to 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.
Ceramics:
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 with small particles, large surface areas, high activity. Adding 1-3% Nano Aluminum to the matrix will prevent densification, enlargement of crystal grain, increased hardness, improved conductivity, mechanical properties and enhanced melting point.
Polishing:
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.
