Reactive Grade Alumina Description

Reactive Grade AluminaReactive grade alumina powders are processed for use as a reactive binder in various applications. With a crystal size of fewer than 2 microns, the Martinswerk reactive grade alumina powders have an Al2O3 content of at least 99.8%. Reactive grades are more stable than calcined alumina, thus suitable for dense, high-strength wear-resistant materials.

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
