What is Aluminium oxide? Aluminum oxide Al2O3 is an inorganic compound. It has high hardness and a melting point at 2054°C. The boiling point is 2980°C. It’s an ionic crystal which can be ionized at elevated temperatures. This is why it’s often used to make refractory materials.
Aluminum oxide is a solid that can hardly be dissolved in water. Although it is easily absorbed moisture, aluminum oxide does not deliquescence. It does not absorb moisture after being burned. Aluminum oxide, a common amphoteric compound (corundum has an alpha-shaped shape and is resistant to acid and corrosion), is almost insoluble and insoluble in organic solvents and water; relative density (d204) 4.; melting point 2050.
Nano aluminum oxide
Coating material for lithium-ion battery separators:
The ceramic coating of Nano-Aluminum Oxide, a high-purity nano-aluminum oxide, is used for the negative and positive electrode separators in lithium batteries. It plays a key role in high-temperature resistance and insulation. The battery is short-circuited after it has been melted.
Materials additives for lithium batteries cathode materials:
Nano-Aluminum dioxide high-purity, doped lithium cobalt or lithium manganate. Can improve thermal stability and cycle performance as well as overcharge resistance. It also inhibits oxygen generation and LiPF6 decay. The electrochemical specific capacitiy loss can be reduced, which will increase LiCoO2’s Electrochemical Specific Capacity.
Carriers Catalyst
High-purity g-type Nano- Aluminum oxide A porous material with a high level of activity, strong adsorption capability, and an internal surface area up to hundreds if not thousands of meters. It’s a common adsorbent, catalyst and carrier in the petroleum refinery and petrochemical industries. Its drying ability is comparable to that of the phosphorus pentoxide. You can reuse it after use by heating the container at 175°C for 6-8h.

Powder coating is anti-caking
The use of nano aluminum oxide in powder coatings is a great way to increase bulkiness. It also has an anti-caking function. Nano-Aluminumoxide can prevent powder coatings agglomerating during summer.
Use this wear-resistant hardener to protect coatings, rubber, or plastics
A prepared coating that contains 5-20% Nanoaluminum oxide can be greatly improved in wear resistance and scratch resistance. The coating is typically 2-5 times stronger than conventional coatings. Nano-Aluminumoxide can be used to create a fine network structure on the paint’s surface that protects the polymer paint layers below. Nano paint’s anti-scratch ability is 3x better than that of original. This paint can be widely used for automobile paints. The coating can be made harder by using Nano aluminum oxide. This can increase its hardness to about 6-7H. This does not impact the coating’s transparency.
Plastics, rubbers adhesives, coatings, and plastics with thermal conductivity:
A single aluminum oxide crystal has a thermal conductivity value of 30. However, Nano-scale Aluminum dioxide has a high thermal conductivity as well as a great deal of spherical filled. Coupling agents, which are surface treatments agents that improve thermal conductivity without altering the mechanical properties of the matrix material, can be useful to increase compatibility of resin matrix and filler.
High purity and uniform size of the nano-alluminum oxide particles make it very dispersible. VK-30 can be used to raise the molding pressure of sintered ceramics and decrease the number pores. This will increase density in the ceramic green body and enhance the mechanical properties and density of the Aluminum oxide ceramics.
Powder metallurgy
Nano Aluminum oxide can be used for metalurgical purposes, having small particles, high specific surface area and high activity. To prevent matrix densification and to increase the crystal grains, Nano Aluminumoxide is added at 1-3%. This will enhance hardness and conductivity.
Aluminum oxide features uniform particles with a large spherical form. Aluminum oxide is used as a polishing material and for metalographic polishing. You can use it for mirror polishing in stainless steel, titanium, cast iron, and stone polishing.
