Abstract
The article presents the results of the estimated assessment of the clay raw materials of the West Kazakhstan Pogodaevsky and Taskalinsky fields. The calculation was made by the chemical composition of clays, focusing on the formation of low-melting triple aluminosilicate eutectics. Based on the calculated data, the melt formation dynamics curves were built, from which the possible sintering degree, sintering intervals and the recommended firing temperature were determined. A forecast was made for a change in the properties of clay raw materials with the introduction of 2% alkaline oxides. The optimal directions of use of these clays and firing parameters are determined.
