Features are established for the occurrence of thermal processes, making it possible to control them, and use the data obtained in developing ceramic acid-resistant material firing regimes. The least coefficient of effective thermal conductivity of acid-resistant materials lies in a temperature range within which the intensity of physicochemical processes is more marked. These zones correspond to the most complex firing conditions, since the lower thermal conductivity, the slower an object heats up.
