Über Titanselenide und ‐telluride

Abstract: Auf synthetischem Wege werden Titanselenide und ‐telluride im Konzentrationsbereich AB ⟷ AB2 dargestellt. Diese Präparate werden röntgenographisch, pyknometrisch und magnetisch untersucht. In beiden Systemen handelt es sich um einen homogenen Übergang des NiAs‐ in das CdJ2‐Gitter: . Dabei durchlaufen die Gitterkonstanten der a‐Achsen bei der Zusammensetzung AB∼1,2 ein Maximum und die der c‐Achsen ein Minimum. Die pyknometrisch gefundenen Molvolumina werden mit den Rauminkrementen nach Biltz verglichen. Magn… Show more

“…In the system titanium-selenium, Ehrlich [66] describes a complete series of solid solutions from TiSe to TiSe z , with a hexagonal structure and continuously changing lattice constants. The structure is described as nickel-arsenide-like at the composition TiSe and cadmium-iodide-like at the composition TiSe z .…”

“…Much of the early work was restricted to the preparation and crystallographic characterisation of polycrystalline samples of the chalcogenide phases. In the titanium-sulphur system, for example, there exists monoclinic TiS 3 , hexagonal TiS 2 , pseudo-hexagonal Ti 2 S 3 , hexagonal Ti 3 S 4 , rhombohedral Ti(1+x)S (x=O.I), three hexagonal modifications of TiS, and hexagonal Ti6S, [60][61][62][63][64][65] Studies of the titanium-selenium and the titanium-tellurium systems [66][67][68][69][70], the zirconium-sulphur system [71,72], the zirconium-selenium [73] and the zirconiumtellurium [74] systems and the hafnium-sulphur system [75] show a similar complexity. Although it was established that most of the MX z compounds had the cadmium iodide layer structure, only fortuitously were single crystals of these compounds prepared and no systematic attempt to grow single crystals was possible.…”

“…In verschiedenen Veroffentlichungen wurde uber die im Titan-Sauerstoff-System auftretenden intermedilren Kristallarten berichtet (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33). Der Hauptanteil dieser Information beruht auf der chemischen und strukturellen Identifizieruiig von TiO, Ti20,j und Tion (23)(24)(25)(26)(27)(28).…”
