Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between grams Cr2O3 and mole. Chromium oxide occurs in nature as a rare mineral called eskolaite. Its main applications are as a gree colorant for glass, inks and paints. Glaze Color: Chrome-tin pinks move toward purple in glazes with significant boron.

Cr2o3

The structure is three-dimensional. Cr3+ is bonded to six equivalent O2- atoms to form a mixture of edge, corner, and face-sharing CrO6 octahedra. The different oxidation states of chromium allow its bulk oxide form to be reducible, facilitating the oxygen vacancy formation process, which is a key property in applications such as catalysis.

Cr 2 O 3 has the corundum structure, consisting of a hexagonal close packed array of oxide anions with 2 ⁄ 3 of the octahedral holes occupied by chromium. The nonabsorbable form of chromium ((51)Cr2O3) and water-soluble and more absorbable Na2(51)CrO4 (the hexavalent form of Cr) were compared. Total retention of chromium given orally ranged around 15 percent of the dose, regardless of the chromium compounds applied.
