Dense and porous thermal-insulating ceramic materials were obtained from the flotation tailings of coal sludge of the processing plant of Inta town. The thermal behavior, changes in the phase and chemical composition during firing in the temperature range from 800 to 1280 °C were studied. During firing, carbonates dissociated, magnetite oxidized, kaolinite amorphized, layers in layered silicates compressed, at 1100 °C cristobalite and spinel were formed, at 1150 °C – mullite, the content of the amorphous phase increased. Dense ceramic materials were obtained at firing temperatures of 800 – 1150 °C, and porous materials at temperatures 1200 – 1280 °C. The physical, mechanical and technical characteristics of the obtained ceramic materials were studied. Porous ceramics, sintered at 1280 °C, belongs to the class of heat-insulating materials with increased thermal conductivity.
