闪锌矿作为一种重要的金属硫化物已得到广泛的研究。但在对闪锌矿中杂质Fe存在形式的认识上却存在许多问题。本文对不同含Fe量的天然闪锌矿测定并分析了Fe的K边EXAFS谱，同时对低温光吸收谱及穆斯堡尔谱进行了研究。结果表明，Fe在闪锌矿中主要以六配位形式存在。经过对各种实验结果及闪锌矿中FeS出溶过程的综合分析，我们得出如下结论：闪锌矿中的杂质Fe主要以六配位形式存在，其中大部分处于尺度在纳米至亚微米的FeS出溶过度微区中，小部分处于尺度在亚微米以上的已出溶FeS微区中，余下的部分在闪锌矿中以填隙及替位形式存在。这与传统认识不同。根据这一新的认识对光吸收谱进行研究，解决了传统认识中光吸收谱与晶体场理论严重不符的矛盾。
Sphalerite has been extensively studied as an important metal sulphide. However, there are still many problems in understanding the existence of Fe in sphalerite. In this paper, K-edge EXAFS spectra of Fe with different Fe-containing natural sphalerite were measured and analyzed. At the same time, low-temperature optical absorption spectra and Mossbauer spectra were studied. The results show that Fe is mainly present in hexacoordinated form in sphalerite. After a comprehensive analysis of various experimental results and the process of FeS dissolution in sphalerite, we conclude that the impurity Fe in the sphalerite mainly exists in the hexacoordinate form, most of which are in the range of nanometer to submicron Of the FeS over-microdomains, a small part of which is in the sub-micrometer scale of the dissolved FeS microdomains and the remaining part of which is present as interstitials and substitutes in the sphalerite. This is different from the traditional understanding. According to this new understanding of the light absorption spectrum research, to solve the traditional understanding of the light absorption spectrum and crystal field theory does not match the serious contradiction.
