Chemical Vapor Transport of Ternary Indium Molybdates An isothermal section of the phase diagram of the system In/Mo/O at 1273 K was established by isothermal equilibration and XRD analyses of quenched samples. The chemical vapor transport of In 2 Mo 3 O 12 was investigated in dependence on mean transport temperature (823 K to 1123 K) and amount of transport agent (Cl 2 or Br 2 ). The observed transport behaviour is compared with results of thermodynamical calculations and the influence of mean temperature, transport agent and moisture contents is described in detail. Single crystals of the metal rich compound InMo 4 O 6 were grown by chemical vapor transport in a temperature gradient 1273 K to 1173 K using H 2 O as transport agent. The gaseous compound In 2 MoO 4 (g) accounts for the chemical vapor transport of molybdenium compounds in the metal rich part of the ternary phase diagram In/Mo/O.
