Abstract: Mercuric iodide crystals in their platelet habit were grown by the polymer controlled vapor transport method. Mercuric iodide 99% in purity was sublimated at temperatures about 122 -126 °C and vacuum conditions (10 -5 mmHg), after selecting an appropriate polymer. Temperature profiles and experimental heat transfer models were determined for two growth furnaces using different insulator configurations for the cold extreme (air, ceramic wool, grilon, copper and ceramic wool).Growth conditions for few and separa… Show more

“…Polymer and iodine were added in solid state. The polymer employed has previously given good results when used for growing mercuric iodide platelets [35]. The growth was carried out in a resistance-heated horizontal furnace, in which a temperature stability of the source of ± 0.2 K was achieved.…”

“…Mercuric iodide is one of the most suitable semiconductor materials for gamma ray and X-ray detectors operating at room temperature because of its favorable characteristics such as high atomic number of its constituent elements and large band gap (2.13 eV), resulting in a high photopeak efficiency [1][2][3][4][5]. Though detector properties of polycrystalline HgI 2 are not yet comparable to that of single crystal HgI 2 , polycrystalline films of HgI 2 are of renewed interest to be used as one of the promising direct converters in X-ray digital radiography because of the lower fabrication cost for large area detectors and practical experience gained with HgI 2 material in space and commercial applications [6][7][8].…”
