摘要
对采自不同类型矿床,含铁量不同的闪锌矿作了比磁化率和红外光谱的测定,某些样品作了晶场光谱测定。作了比磁化率的理论计算,并讨论了Fe^(2+)和Fe^(3+)在晶体中对磁化率的贡献。从理论上对闪锌矿的晶场光谱作了分析,并解释了闪锌矿颜色与杂质的关系。讨论了红外光谱的特点。
The magnetic susceptibility and infrared spectra of sphalerites from various types of deposits with different Fe content were mea-sured. The crystal field spectra were also measured for some of the samples. Then the susceptibilities were calculated theoretically. contri-butions of Fe^3-and Fe^2-inos were discussed. The crystal field spectra were analysed and an interpretation was given to the color changeof sphalerite and its relation to impurities. The infrared spectra were discussed.
