摘要

在tis2 /NbS 2、tis2 /NbSe 2、NbS 2 / tas2和NbSe 2 /TaSe 2体系中，通过粉末x射线研究发现了tis2 /NbS 2、tis2 /NbSe 2和NbSe 2 /TaSe 2的固态完全混相。以碘为输运剂，在1000 ~ 900℃的温度梯度下，通过化学蒸汽输运反应可以制备混合晶体和二元化合物。tii3 (g)、tii4 (g)、nbi4 (g)和ta4 (g)是产生输运效应的气体组分。

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

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.

期刊介绍： Zeitschrift fuer Naturforschung B (ZNB) publishes novel research in all areas of inorganic chemistry, organic chemistry, and analytical chemistry. In particular, the journal focuses on solid state chemistry, coordination chemistry, main group element chemistry, synthetic organic chemistry, natural product chemistry and, to a lesser extent, on analytical chemistry. For more than 65 years Zeitschrift fuer Naturforschung B has been open to contributions from all fields of experimental and theoretical chemistry. Zeitschrift fuer Naturforschung B publishes 12 issues per volume/year. Sometimes double issues occur. Topics Solid state chemistry Coordination chemistry Main group element chemistry Organic chemistry Natural product chemistry.
