Spherical Al2O3 Powder Properties And Applications

The chemical formula for aluminum oxide is Al2O3. The compound is white, powdery and high-hardness. It has a melting point at 2054 degrees Celsius and a boil point at 2980 degrees. It is a crystalline ionic compound that is ionized by high temperatures. Aluminum oxide exhibits characteristics such as high dispersibility (higher than water), insulation, a stable phase of crystal, high hardness and good dimensional stability.


Spherical Al2O3 Powder

This is a powdered alumina that’s made from high-purity random alumina, which has undergone high-temperature melting and spray calcination. Then it goes through sieving and purification. The product possesses high thermal conductivity as well as high insulation, hardness, resistance to high temperatures, wear resistance and corrosion resistance. The product has excellent and unique characteristics, including good fluidity and low oil absorption. It also features high spheroidization with high alpha phase, a small specific surface, and a controllable particle-size distribution.

Al2O3 Powder Properties of Spherical Al2O3 Powder

High filling

The high-density mixing of epoxy and silica can produce a mixture that is low in viscosity with good fluidity.

High Thermal Conductivity

Due to its spherical shape, it is able to provide multi-directional heat transfers, good dispersion of the thermally conducting products in the system and high thermal conduction;

Low Wear

Its sphere shape reduces abrasion on mixers, molding machines and other equipment and increases the equipment’s life.
