Abstract
This article discusses the results of the study of proppants obtained from domestic raw materials - bauxite, kaolin and white clay, sand, as well as fly ash by nuclear gamma resonance spectroscopy (the Mossbauer effect) and X-ray fluorescence analysis. The hyperfine structure, electronic states and elemental composition of proppants are given. The results of the study of volatile ash obtained during pulverized coal burning of Ekibastuz, Shubarkul, Karazhyralinsky deposits at thermal power plants are analyzed. According to the results of the studies, various combinations of complex phases and the elemental composition of proppants were determined using Mossbauer spectroscopy and X-ray fluorescence analysis. The Mossbauer measurements were carried out on the MS1104Em spectrometer in the constant acceleration mode with a 57Co source in a chromium matrix at room temperature. The elemental composition of samples of proppants based on fly ash was determined using an energy dispersive X-ray fluorescence spectrometer (RFS) at the EDX-7000 installation of SHIMADZU.
