Horizontal Zone Refining of Indium Iodide (InI) Polycrystal

The indium iodide (InI) polycrystal which was synthesized by two-zone vapor transporting method was purified by using horizontal zone refining method. Preparation process on high quality and single phase InI polycrystal was successfully fixed. The lattice structure, morphology, component and impuritily concentration of InI crystal were investigated by X-Ray Diffraction (XRD), Scanning Electron Microscope-Energy Dispersive Spectrometer (SEM-EDS) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The results indicate that the InI polycrystal after refinement has better lattice structure and higher quality than before.
