Use of slimes flotation coal enrichment in ceramic masses on the basis of interslate clay without application of traditional natural materials allows to obtain heat-insulating materials with heat conductivity and density accor-dingly less than 0,20 W/(m×°С) and 1200 kg/m3. Carbonaceous wastes (slimes flotation coal enrichment and waste products of combustible slates) not only increase the porosity of pottery, but also contribute to uniform sintering of the ceramic crock. Obtaining ceramic material from power system waste without application of traditional natural raw materials promotes recycling of industrial wastes, environmental protection and expansion of raw materials base for production of construction materials.
