Overview

Description

Chromium(III) oxide is the inorganic compound of the formula Cr2O3. It is one of principal oxides of chromium and is used as a pigment. In nature, it occurs as the rare mineral eskolaite.

Application

Chromium(III) oxide is the precursor to the magnetic pigment chromium dioxide. It is one of the materials that are used when polishing the edges of knives on a piece of leather (also called stropping).
