Legma %J Bulletin of the Chemical Society of Ethiopia %D 2008 %I Chemical Society of Ethiopia %X Polycrystalline niobium-doped molybdenum and tungsten diselenides were synthesized in silicatubes sealed under secondary vacuum. They were characterized by scanning electron microscopy, electrondiffraction, X-ray diffraction, chemical composition and EDX analyses. The morphology of niobium-dopedmolybdenum solid solutions was shown to depend strongly on the conditions of synthesis, whereas the structuralcharacterization did not. %K Polycrystalline niobium-doped molybdenum and tungsten diselenide solid solutions %K Doped %U http://www.ajol.info/index.php/bcse/article/view/61289
