Abstract
By the method of heat treatment, a mixture of graphite and salts was obtained from the foam graphite and the conditions for its effective production were determined. The composition of natural graphite of the GL-1 grade of the Russian deposit was determined. The study shows that the main element in graphite is a mixture of carbon and other elements. The analysis of energy dispersions showed the content of other elements in graphite. The content of Zn in the penografite obtained by elemental analysis was determined. In addition, the physicochemical properties of heat-treated graphite were investigated. Using IR spectroscopy, it was found that there are different groups on the surface of the penografite. Analysis of the CS-spectra of penografite allowed us to determine the structure of graphite and penografite. The conducted studies have shown that penografite differs depending on the forms of the spectrum, a set of spectral characteristics that allow us to quantify the degree of maturity of the crystal lattice and identify various defects. Raman spectroscopy for a full understanding of the results of the analysis, studies were carried out scanning electron microscopy (SEM) on a layered structure of penografia. The result of microanalysis and heat treatment shows that natural graphite has changed its composition and structure. It is established that the high-temperature thermal effect significantly changes the quantitative composition of the mixture and the content of various elements depends on the temperature of the thermal cover. The EDAX spectra of heat-treated graphite are shown.
