DEVELOPMENT OF STRUCTURE OF CERAMIC BRICK WITH REGARD TO ENVIRONMENTAL FACTORS
Preliminary studies have established that the process of burning ceramic bricks containing coke-fines as burn-in additives proceeds much faster, with minimal energy expenditure than the traditional method. Also, under these conditions, it is established that the coke fines serve as a reducing agent and accompanies the decomposition of difficult to decompose salts (Na2SO4, CaSO4), which eliminates such negative phenomena as high education. The reducing medium also positively influences the reduction of iron oxides (Fe2+ to Fe+ ) contained in loess-like loam, the chemical ratio of which is Fe+ more active than Fe2+, which predetermines the acceleration of the formation of the liquid phase. Further heating of the sintered material layer leads to a decrease in the viscosity of the liquid phase, thereby enveloping the grain of the refractory component, or dissolves in them, forming new chemical compounds.
