Reactions of chromium oxides and chromium metal with disodium oxide

Abstract

The ternary oxides NaCrO2, Na3CrO4, and Na4CrO4 are characterised by X-ray powder-diffraction patterns. The compound NaCrO2 has been prepared from equimolar quantities of Na2O and Cr2O3, but Na4CrO4 is formed at higher concentrations of Na2O or from reaction of Na2O and Cr. The ternary oxide NaCrO2 decomposes reversibly to simple oxides at ca. 795 °C.
