Studies have shown that it is advisable to use high-alumina nanotechnological raw materials as a softener to increase the thermal stability of clinker bricks. With an increase in the compositions of the ceramic masses of aluminum oxide Al2O3, the thermal resistance increases, and the TLEC decreases during firing (1250 ° C) of clinker bricks. When the content of Al2O3 in ceramic masses is from 41 to 43%, the thermal resistance of clinker bricks reaches a maximum value and lies in the range from 11 to 13 cycles. As a result of regression analysis, a mathematical model was obtained that allows one to determine the thermal stability of clinker bricks at points that were not included in the series of experiments.
