Thermodynamic modelling of the ternary systems M / Q /I ( M = Sb, Bi, Q = Se, Te) indicated solid‐gas equilibria suitable for chemical vapour transport of bismuth and antimony chalcogenides. The predictions of the modelling were confirmed by transport experiments on a transport balance. The optimum transport conditions using iodine as transport agent were determined for all systems to: ϑ source = 500 °C and ϑ sink = 450 °C. For Δ T > 50 K the sequential transport of chalcogenide iodides MQ I followed by M 2 Q 3 occurs. Thermodynamic standard data of the gas species SbI(g) were concluded from equilibrium calculations: ΔH 0 f,298 (SbI(g)) = 106 ± 3 kJ·mol –1 ; S 0 298 (SbI(g)) = 255 ± 3 J·mol –1 ·K –1 ; C p (SbI(g)) = 37 ± 1 J·mol –1 ·K –1
