Thermodynamic Studies of High-Temperature Processes in the System "Loesslike Loam - Coal - Alkaline"

Abstract

In recent years, studies of a number of foreign scientists have been reported on the possibility of using loess loam as the main constituent of the ceramic composition in the production of clinker brick. Loess loam is considered a common raw material. In this paper, we consider the purpose, which is research on the study and development of methods that regulate the physicochemical processes occurring in the mass of loess-like loam under the influence of temperature. As a result of these studies it will be possible to intensify thermochemical processes and achieve high-quality products with minimal energy costs. Thus, the possible chemical interactions between minerals of loess-like loam have been theoretically studied, the medium of which is given priority to the decomposition of kaolinite. To intensify the decomposition process of refractory minerals, it is recommended to use an alkali additive in an amount of up to 5%, with a weight ratio of coal.
