＜正＞The solid state synthesis can be carried out by using the initial pure metal zinc and inorganic sulfur powder mixtures by means of the mechanochemical synthesis route. The completion of solid state reaction between pure zinc and sulfur powder to produce c-ZnS and h-ZnS phases via such a route was rather fast, as compared to other non-sulfide systems by the similar method. The study was aimed to investigate the microstructure development and phase formation through the solid state reaction by controlling the processing parameters involved in this process including grinding media to powder weight ratio, solid state reaction duration, reaction atmosphere, stoichiometric ratio of zinc and sulfur elements, grinding media and choice of minor additives such as teflon-based polymeric lubricants and transition metal dopants （Mn, cu）. Both as-synthesized powders and heat-treated ZnS materials with various stoichiometric ratios were characterized by XRD, EXAFS and XANES analysis. The interesting results from X-ray absorption spectroscopy （XAS） would provide us some strong evidence whether stoichiometric and non-stoichiometric ZnS material can be successfully formed. The minor amount （0.5 wt%）of Mn+2 or cu+2 ion dopants added to the powder batch with the Zn/S stoichiometric ratio between 1.00 to 1.05 was found to favor the reaction rate in the mechanochemical synthesis. Moreover, the obtained results of ZnS phase development under reaction conditions and different transition metal dopants in this study would imply that synthesis of other kind of sulfide compounds can be achieved using the demonstrated technique.
