【 摘 要 】

The article presents the results of phase composition analyses of Zn-Pb slags based on selected structural tests. Based on these tests it has been found that the application of several complementary research techniques may provide reliable information regarding the presence of individual phases. In view of obtaining qualitative characteristics of the components of slags, the phase identification tests by means of X-ray diffraction were found to be precise. Based on them, also the percentage of the individual crystalline phases and the percentage of the amorphous substance have been determined. Studies using electron scanning microscopy and X-ray spectral microanalysis allowed for the determination of the chemical composition of the individual components. In that case, the X-ray spectral microanalysis was found to be more precise and it allowed for the identification of substitutions of elements occurring in small amounts in the crystalline phases, i.e. the rare earth elements.
