Chromium oxide Cr2O3

Chromium oxide is an inorganic compound with the formula Cr2O3. It is one of the principal oxides of chromium.
In nature, it occurs as the rare mineral eskolaite. Cr2O3 is a hard, brittle material (Mohs hardness 8 to 8.5). It is not readily attacked by acids.
Chromium oxide is a well known catalyst for the complete oxidation of chlorinated hydrocarbons due to its high removal activity.

Mainly used in metallurgy, paints, refractory materials and ceramics industries.
