Results of producing the frost resistance wall ceramic from a low-quality alumosilicate claye raw material – loam, with involvement in the production of from 10–30% of fuel slag by semi-dry pressing are presented. The results of studies of experimental materials – loams of Buguruslan and Novosergiev deposits, fuel slag are presented. The composition of the charge for the development of ceramic products is determined. The expediency of the addition of container glass in the form of glass cullet in the amount of 10% is revealed. The composition of additives of fuel slag and glass cullet to loam under conditions of pyrogenic synthesis helps to reduce the temperature of the beginning of formation of a liquid phase, increase the amount of melt and the formation of new anortite – and wollastanite-like crystalline phases, taking part in the formation of the fine-porous structure of the ceramic material. These processes of structure and phase formation make it possible to produce the ceramic of improved frost resistance.
