Název v původním jazyce
Magnetization as an effective tool for kinetics evaluation in mechanochemical synthesis of chalcopyrite CuFeS2
Popis výsledku v původním jazyce
Copper, iron, and sulphur in elemental form were applied for mechanochemical synthesis of chalcopyrite CuFeS2. Products of synthesis were characterized by XRD method and evaluated by Rietveld analysis. A mixture of cubic (JCPDS 75-6866) and tetragonal (JCPDS 37-0471) phases of chalcopyrite with almost identical diffractograms were identified. Both phases are nanocrystalline with sizes 13 nm and 7 nm for laboratory and industrial milling, respectively. For determination of iron consumption during the synthesis, method of magnetometry has been applied. Based on magnetization data reflecting time dependent incorporation of elemental iron into chalcopyrite nanostructure, the kinetics of the synthesis was evaluated. From kinetic data the rate constant of reaction k,as well as the conversion degree R were determined.
