Chemischer Transport fester Lösungen, 25 [1]. Untersuchungen zur Mischphasenbildung und zum chemischen Transport in den Systemen TiS 2/MoS 2, TiSe 2/MoSe 2, TaS 2/MoS 2 und TaSe 2/MoSe 2

X-ray investigations have shown a complete miscibility in the systems TaS 2/MoS 2 and TaSe 2/MoSe 2. In these systems mixed crystals could be obtained by chemical vapour transport with iodine as transport agent in the temperature gradient 1000 → 800°C. By contrast, no mixed crystals are formed in the systems TiS 2/MoS 2 and TiSe 2/MoSe 2. The transport behaviour in these systems is reported. © 2005 Verlag der Zeitschrift für Naturforschung

Chemischer Transport fester Lösungen, 26 [1]. Untersuchungen zur Mischphasenbildung und zum chemischen Transport in den Systemen TiS 2/NbS 2, TiSe 2/NbSe 2, NbS 2/TaS 2 und NbSe 2/TaSe 2

In the systems TiS 2/NbS 2, TiSe 2/NbSe 2, NbS 2/TaS 2 und NbSe 2/TaSe 2 complete miscibility in the solid state has been observed by powder X-ray investigations. Mixed crystals as well as the binary compounds can be prepared by chemical vapour transport reactions using iodine as transport agent in the temperature gradient 1000 → 900°C. The gaseous species TiI 3(g), TiI 4(g), NbI 4(g) and TaI 4(g) are responsible for the transport effect. © 2005 Verlag der Zeitschrift für Naturforschung
