【 摘 要 】

The study of the matrix structure of ceramic brick made from carbonaceous mudstone tailings of Korkinsky coal opened pit mine is presented in the current paper. This study includes a thin sections analysis by the polarizing microscope, X-ray, SEM and infrared spectra investigations. It has been discovered that processes of solid- and liquid-phase sintering with the formation of new mineral phases occur inside and on the surfaces of granules during firing. It is shown that a liquid phase is formed in the matrix. It fills inter-grain gaps and connects mineral particles between themselves. It has been found that the advanced physical and mechanical properties of ceramic bricks obtained by creation of the matrix ceramic crock structure, intensive forming of a glass phase on the boundary of the section medium of ceramic composite and temperature reduction of the processes of solid-phase sintering.
