Chromium oxide Usage And Synthesis
Chemical Properties green crystalline powder
Chemical Properties Chromium oxide is a bright green, odorless powder
Uses Chromium(III) oxide is used as pigment for coloring green on glass and fabrics. Other important applications are in metallurgy; as a component of refractory bricks, abrasives and ceramics; and as a catalyst in hydrogenation, hydrogenolysis and many other organic conversion reactions. It also is used to prepare other chromium salts.
