Calcined Alumina Description

Calcined alumina is produced through the calcination (“heating”) of alumina to various temperatures. By controlling the calcination temperatures and time, the properties of the alumina can be controlled. Calcined alumina is therefore utilized in a variety of industrial applications including Structural ceramics, Technical ceramics, Polishing compounds for plastic, metal, and glass, Fillers for Rubber and Plastics, Friction - anti slip, Refractories, Paint & Coatings and Thermal Spray Powders.

Features:

-High Hardness

-High Compression Strength

-Abrasion/ Wear-Resistance

-Abrasives

-Chemical Inertness

-High Degree of Refractoriness

-Superior Electrical Insulating Properties

-Dielectric Properties

-High Melting Point
