The researches’ results show that it is possible to obtain a ceramic crock, which water absorption meets the requirements of facade ceramic tiles at a charge firing temperature of 1150 ° C, consisting of 60% low-melting and 40% refractory clay raw materials from deposits in the Novosibirsk Region. Additives influence nature of directed action was studied: wollastonite and cullet by the mathematical planning method of the experiment. It was found that the introduction of additives helps to improve the physical and mechanical properties of the ceramic crock. The introduction of 10% cullet allows increasing the tensile strength by 10.3% compression and reducing water 27.1% absorption. The amount of 15% wollastonite contributes to a greater increase in mechanical strength and a decrease in water absorption, compared with the control composition. The joint introduction of mineral additives leads to a decrease in tensile strength A method for producing high-quality facade and building ceramics from low-grade, poor in clay minerals raw materials with carbonate inclusions, which consists in mechanically activating these raw materials and purposefully creating a hierarchical structure of semi-dry pressed products, is proposed in the research work. The developed technology of preparing a press-mass that is uniform in humidity and dispersion by rolling mechanically activated powders based on aggregate grains (micro level), firmly coated with clay mineral nanoparticles, to the state of spherical granules (macro level). This approach to mass preparation significantly improves the subsequent stages course of pressing and firing products. Its effect is the possibility of obtaining various types of building and facade ceramics with high performance characteristics.
