Product Description

Al2O3 Alumina Spherical Powder 5-20um
Al2O3 Alumina Spherical Powder 15-45um
Alumina Al2O3 Powder 45-73um
Spherical alumina is basically alumina  "shaped" in a high temperature fusion process. Spherical alumina therefore has the same intrinsic properties as any other alumina. Its chemical formula is Al2O3.
At Sibelco high purity aluminas are being used to make spherical alumina.Aluminium Oxide is a white powdery material, Al2O3 has good electrical insulating properties while having relatively high thermal conductive properties (36 Wm−1K−1), furthermore characterised by:
High thermal conductivity
High inertness in various media
High density and, as a result, low oil absorption
High Mohs hardness of 9
High Refractive Index of 1.76


Specification
High thermal conductivity gel, high thermal conductivity gasket, electronic oackaging and other industries

Spherical Al2O3 powder, alumina spherical shape powder, because of its high melting point, good thermal stability, good wear resistance, high mechanical strength, good electrical insulation, excellent corrosion resistance and other characteristics, is widely used in the electrical and electronic industry; Alpha alumina spherical shape powder as a filler in rubber and resin, the thermal conductivity of the mixture can be remarkably increased, the expansion coefficient can be reduced, and the strength of the mixture can be increased. Alpha Al2O3 spherical shape powder can be evenly dispersed in the organic body and the formation of the most closely stacked, get high filling, low viscosity, high thermal conductivity mixture. In same time, alpha Al2O3 spherical shape powder can reduce wear and tear of mixer, molding machines and mold equipments to extend the service life of equipments.
