    Description / Table of Contents: Es wurde die thermische Zersetzung von NH4-Tetrathiowolframat, (NH4)2WS4, und die Natur der entstehenden Wolframsulfide röntgenographisch, differential-thermoanalytisch, lichtmikroskopisch und durch ESR-Messungen untersucht. Bei 200°C kann nicht-stöchiometrisches Wolframtrisulfid erhalten werden. Beide Sulfide ergeben charakteristische ESR-Spektren.
    Notes: The decomposition of ammonium tetrathiotungstate, (NH4)2WS4, and the nature of the resulting tungsten sulfides have been studied, mainly by X-ray diffraction, differential thermal analysis, optical microscopy and electron spin resonance.Non-stoichiometric tungsten trisulfide may be obtained by decomposition of (NH4)2WS4 at about 200°C. At 330°C crystallization of tungsten disulfide starts. Characteristic electron spin resonance spectra have been obtained for both sulfides.
