General Information

The chemical formula of Cr2O3, also called Viridian, can be used in many industries.

Molecular Structure

Cr + 3 O-2 Cr2O3

Production and Reactions

Chromium (III) is reacted with aluminum or silicon to produce chromium metal.

Cr2O3 + 2Al ---> 2Cr + Al2O3

2Cr2O3 + 3Si ---> 4Cr + 3SiO2

With the addition of 1% at low temperatures, the shades of yellow lead are obtained in the acidic secrets. The increasing ratios of SiO2 cause a color change from brown to green on a chrome red glaze.
