Polycrystalline niobium-doped molybdenum and tungsten diselenides were synthesized in silica tubes sealed under secondary vacuum. They were characterized by scanning electron microscopy, electron diffraction, X-ray diffraction, chemical composition and EDX analyses. The morphology of niobium-doped molybdenum solid solutions was shown to depend strongly on the conditions of synthesis, whereas the structural characterization did not.

Results of investigations on electronic (electrical conductivity and thermoelectric power) and electrochemical properties of non-stoichiometric tungsten diselenide are presented in the paper. It is proved that holes connected with non-stoichiometry (W , -xSe,) are the dominating current carriers within the temperature range 77 to 300 K. A qualitative scheme of the electronic structure of W, -*-Se, is proposed.A strict correlation between the electronic and electrochemical properties of tungsten diselenide is proved for the cell of Li/Li+/Li,W, -.Se, type.
