Thermodynamics analysis of indium iodide polycrystal synthesis

According to the thermodynamics analysis, the molar enthalpy change, the molar entropy increase, the Gibbs free energy change and the balance constant of indium iodide polycrystal synthesis reaction were calculated in order to evaluate the feasibility of reaction temperature on 653 K. After the temperature 653 K was applied in the synthesis experiment, indium iodide polycrystal was successfully obtained by the two‐zone vapor transporting method. The result of X‐ray diffraction analysis indicates the temperature 653K can be used for indium iodide polycrystal synthesis. According to the thermodynamics analysis, an appropriate reaction temperature was calculated for indium iodide polycrystal synthesis reaction. Indium iodide polycrystal was obtained by the two‐zone vapor transporting method after the temperature was applied in the synthesis experiment. The result of X‐ray diffraction analysis indicates the temperature and thermodynamics analysis can be used for indium iodide polycrystal synthesis.
