It is a white, insoluble solid, tasteless and odorless, and extremely tough. The melting point for aluminum oxide is 2054 while the boiling point for it is 2980. Aluminum oxide is a common amphoteric oxide. It dissolves in alkaline and inorganic acids, and is nearly insoluble in water.
Why is Aluminum Oxide Al2O3 so important?
Fillers
Aluminum oxide, which has a chemical inertness and is white, is the most popular filler for plastics. Aluminum oxide is often used as a sunscreen ingredient and can also be found in cosmetics like blush, lipstick, and nail polish.
Glass
Aluminum oxide is an ingredient in many glass formulations. Aluminum oxide is an ingredient in many glass formulations. Aluminosilicate glasses are a common type. They usually contain 5-10 percent.
Catalytic
Aluminum oxide can catalyze a wide range of industrial reactions. The Krauss process, which converts hydrogen sulfide exhaust gases into elemental sulfur in refineries, is the most common use of aluminum oxide. It can also dehydrate alcohols to alkenes.
Aluminum oxide can serve as a catalyst carrier for many industrial catalysts such as those used for hydrodesulfurization, and certain Ziegler-Natta polymerization reaction.
Gas purification
Aluminum oxide is used widely to remove water in the airstream.
Abrasive
Aluminum oxide is used to increase its hardness, strength. Natural corundum (an aluminum oxide form) has a Mohs toughness of 9, which is slightly less than diamond. It’s widely used as an industrial abrasive. Many types of sandpaper contain aluminum oxide crystals.
Additionally, it is widely used in grinding operations, including cutting tools, because of its low insulation value and low specific heat. Arroite, a abrasive powder, is used as the main component in the “chalk” at the tip of billiard balls.
Aluminum oxide powder can be used in scratch repair kits and CD/DVD disc polishing. It is used in toothpaste due to its polished finish. It’s also used in microdermabrasion.
Paint
Aluminum oxide flakes are used to create reflective decorative effects in coatings. They can be found in the automotive and cosmetic industries.
Composite fiber
A variety of high-performance applications have been made possible by aluminum oxide in commercial and experimental fiber materials.
What is Spherical Al2O3 Oxide?
Spherical Aluminum Oxide can be used to make aluminum powder. It is made by high-temperature melt injection of an irregular high-purity aluminum oxide and then filtered and purified.
High thermal conductivity, high insulation and high hardness are some of the product’s outstanding characteristics.
Spherical aluminum dioxide is used widely in thermal interface materials and thermal engineering plastics.
What Are the Properties of Spherical Al2O3 Aluminum Oxide?
High Fill
Silica gel and epoxy are able to be filled with high densities and controlled particle size distributions, resulting in a mixture that is low viscosity but good fluidity.
High thermal conductivity
Because it is spherical, it can achieve multidirectional heat transfer, good dispersion within the system and high thermal conductivity with thermal conductive materials.
Low wear & tear”
The equipment lasts longer because of its unique shape.
What is Spherical Al2O3 used for?
Thermal interface materials
Thermal conductive silicone gel, thermal silicone grease, thermal thermal potting adhesive, thermal thermal conductive double-sided glue, phase changing materials, and others.
Thermal engineering polymers
The LED lamp shade, the switch housing, the electronic product housing, heat dissipation elements of electrical products (heat Sink, filler heat dissipation sub-substrate, MC Substrate), etc.
Thermoconductive aluminum base copper clad sheet
High-power LED circuit board, power board, etc.
