摘要：
An alternative method for the synthesis of polycrystalline samples of the phases M(1)Cr(CrO4)(2) (M(1) = Na, K, Rb) is proposed. Crystallographic data of the three isostructural compounds were refined by means of the Rietveld method and their thermal stabilities investigated by TG and DTA methods. The infrared and Raman spectra were interpreted on the basis of a factor group analysis of the internal vibrations of the CrO42- groups.
