What is Al2O3 Aluminum Oxide? The aluminum oxide type of organic has the chemical formula: Al2O3. It has a very high degree of hardness.

It’s a white, insoluble solid that is tasteless, odorless and very hard. The melting point for aluminum oxide is 2054 while the boiling point at 2980. Aluminum oxide is a common amphoteric metal, easily soluble in organic acid and alkaline solutions. However, it’s nearly insoluble in water, and other non-polar organic liquids.

For what purpose is aluminum oxide Al2O3 employed?


Aluminium oxide is a preferred filler in plastics because it’s chemically inert. Aluminum oxide, a popular ingredient in sunscreens, can also be found in makeup such as lipstick, blush and nail polish.


Aluminium oxide can be found in many glass formulas. Aluminium oxide can often be found in common glass types like aluminosilicate.


A variety of industrial processes can be catalyzed by aluminum oxide. The Krauss reaction to transform hydrogen sulfide fumes into elemental sulfur is the most common use of aluminum oxide. You can use it to make alkenes from alcohols.

You can use aluminum oxide as a catalyst carrier to many industrial catalysts such as hydrodesulfurization, and certain Ziegler–Natta polymerization reactions.

Gas purification

Aluminium oxide can be used widely to extract water from the airstream.


Aluminium oxide is used because of its strength and hardness. Natural corundum (an aluminum oxide form) has a Mohs toughness of 9, which is slightly less than that of diamond. It’s widely used in abrasives, and even to replace industrial diamonds. Numerous types of sandpaper contain aluminum oxide crystals.

Additionally, it is widely used for grinding and cutting operations due to its low insulation value and low specific heat. Arroite (a powdery abrasive metal) is used as the primary component in the “chalk”, the material that sits at the end of a cue’s tip.

Aluminium oxide powder can be used to polish CD/DVDs and repair scratches. This powder’s polish is why it is used in toothpaste. Microdermabrasion can be done using it, depending on the instructions of the manufacturer.


For example, in automotive and cosmetic industries, aluminum oxide flakes may be used to create reflective effects in coatings.

Composite fiber

A variety of high-performance, experimentally and commercially available fibers have been made from aluminum oxide.

What Is Spherical Al2O3 Oxide?

Spherical Aluminum Oxide A type of aluminum powder material that is produced by high temperature melting of high purity aluminum oxide. Then, it is processed by screening and purification.

High thermal conductivity, high insulation and hardness are some of the product’s key characteristics.

Aluminum oxide spheres are widely used for thermal interface materials, thermal engineering and filler plates in aluminum base copper clad.

What is Spherical Al2O3 properties?


Silica gels and epoxy are able to be mixed with high densities and controlled distribution of particle sizes. This results in a mix with good viscosity.

High thermal conductivity

Due to its unique spherical form, it is capable of multi-directional heat transport, excellent dispersion and high thermal conductivity.

Low wear & tear”

The equipment lasts longer because of the shape of the ball.

Why is Spherical Al2O3 Useful?

Thermoplastic interface material

You can also find thermal conductive silicone gel, thermal silicone grease, thermal thermal potting adhesive and thermal conductive double side adhesive for phase-changing materials.

Heat engineering plastics

The LED lamp shade, the switch housing, and the electronic product housing are heat dissipation elements of electrical products. These include heat sink, filler heat dissipation sub-substrat, MC substrate, and others.

Thermoconductive aluminum copper-clad base plate

The power circuit board is a high-power LED circuit board.
