Oxide Powder

Spherical Aluminum Oxide Al2O3 Powder CAS 1344-28-1

Item No.: TR-S-Al2O3
Spherical alumina has the characteristics of high sphericity and high content of α-phase alumina, and it shows superior performance when used as a filler for rubber, plastics and ceramic raw materials.
Purity: 99.9%
Shape: Spherical
Performance of Spherical Aluminum Oxide Al2O3 Powder:
1. High filling density: With its large particle diameter and broad particle size distribution, realizes high-density filling for rubber and plastic and produces compounds with low viscosity and good fluidity.
2. High thermal conductivity: High filling density enables production of compounds with higher thermal conductivity and higher heat dissipation rate compared to crystalline silica.
3. Low abrasivity: Due to its Spherical shape, less-wearing of kneading machines, forming machines and dies.
