Popis:	The structural peculiarities of CuCrS2 and AgCrS2 and the phase ratios in the alloys CuxAg 1- xCrS2 (x = 0-1) of these compounds were studied at 293-773 K. CuCrS2 was shown to have unlimited solubility in AgCrS2 in disordered phases. Ion conductivity was measured for all compositions. At the phase tran� sition point, the activation energy of ion conductivity changed abruptly. The chemical diffusion coeffi� cients and ion transport numbers were determined from the setin and decay curves of concentration polarization.
