Disadvantages are noted in the operation of walls with a multi-layer construction with an effective insulation. It has been shown the necessity of creating new efficient building materials and products for the device of single-layer exterior walls, which correspond to the current standards for heat shielding of buildings. The prospect of obtaining effective wall ceramics of cellular structure is indicated. The influence of the temperature and duration of firing on the formation of the structure and properties of cellular ceramics with a glass-ceramic frame has been studied. It has been given an assessment of the raw material components of the mixture according to chemical, granulometric, mineralogical compositions and ceramic-technological properties. The dependences of changes in the physicomechanical properties of cellular ceramic samples on the maximum calcination temperature and duration of isothermal exposure are given. Images of macro- and microstructure of cellular ceramic samples from granular mixture, annealed in the temperature range of 850–1000°C, were obtained by optical and scanning electron microscopy. It has been represented the change in the content of the X-ray amorphous phase and the porosity of cellular ceramic samples at the depending on the firing temperature. Optimal firing parameters have been established that provide the best ratio between strength and average density of cellular ceramic material. An excessive increase in temperature leads to the intensive formation of a pyroplastic phase and an increase in the average density of cellular ceramics by 1.4–1.5 times. The effect of collapsing small cells of the gas phase with each other, their coarsening, migration and exit from the three-phase ceramic system at a temperature of more than 950°C, leading to disruption of the cellular structure and a decrease in the total porosity of the ceramic material. The formation of a melt along the inner surface of the pore cells provides a continuous shell of the glass-ceramic phase and low water absorption of the ceramic material (6.5–7%).
