Abstract

Alkali metal chromium oxides of the formula MCr3O8 can be prepared by thermal decomposition of chlorochromates, trichromates and tetrachromates and by heating chlorochromates or alkali halides with chromium(V1) oxide. The preparation of lithium chlorochromate, LiCrO3Cl, is described and new metastable phases of RbCr2O8 and CsCr3O8 are reported. The temperatures, products and enthalpies of decomposition for LiCr3O8, KCr3O8, RbCr3O8 and two forms of CsCr3O8 have been determined. The decomposition is modified in the presence of alkali halides.
