The results of studying the behavior of analcime-bearing rocks of the Timan region (Komi Republic) under high-temperature firing (1200 – 1280 ?С) were presented. The mineral composition and physical characteristics (apparent density, water absorption, open porosity, thermal conductivity) of the resulting ceramics were determined. The influence of the mineral composition of the initial analcime-containing rocks on the bloating and physical characteristics of fired ceramics was shown. Porous materials with low apparent density (0.37 – 0.39 kg/m3), water absorption (up to 4.3 %), and thermal conductivity (0.09 – 0.10 W/m??С) were obtained. The obtained results show the prospects of using analcime-bearing rocks with a certain mineral composition for producing heat-insulating materials.
