Spherical Al2O3 Powder Properties And Applications

The chemical formula of 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.


Al2O3 Powder – Spherical

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 other purification processes. The product has properties such as high thermal conductivity. high insulation. high hardness. high temperature resistance. corrosion resistance and wear resistance. It has many unique and outstanding characteristics including good fluidity and low oil absorption.

Properties of Al2O3 Powders

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 prolongs their life.
