Ceramic powder 0,60 - 0,85 mm weiss HRC 50 - 65, per kg

Powder of oxide with polycrystalline structure. Good mechanical properties and good corrosion, abrasion and heat resistance. Self-lubricating, lightweight, electrical insulators.
In metal recovery, grinding/polishing is one of the main cost factors, alumina grinding media effectively contribute to the reduction of this industrial cost.
The microspheres have optimal properties (chemical composition, hardness, roundness, specific gravity) and are particularly suitable for use in ultra-fine grinding mills.

Corrosion resistance

Resistant to water, salt solutions, acids, also solid in aggressive environments
Unstable in contact with hydrofluoric acid, hydrochloric acid, warm sulfuric acid and strong alkali solutions
