Chemical Vapor Transport of Solid Solutions. Part 15. Chemical Vapor Transport
of Mixed Phases in the Systems TiS2/TiSe2, TiS 2/TaS2, TiS 2/TaSe 2 and TaS2/TaSe 2.
17- 022 —
X-ray investigations show that TiS2 and TiSe2 as well as TaS2 and TaSe2 are completely miscible in the solid state. Single crystals of the solid solutions can be grown
by chemical vapor transport using iodine as transport agent (1000→900 °C). Thermochemical calculations for the systems TiS2/I2 and TiSe2/I2 show that the transport phenomena is due to the formation of gaseous TiI4. The transport occurs congruently. —
