Object of investigation is local polymineral clay and materials on its basis. The purpose of the work is to determine physical and chemical regularities and ways of directed regulation of ceramic masses sintering on the basis of polymineral clays of Belarus and develop recommendations for their application in the composition of masses for the production of ceramic items for different purpose. Complex investigation has been conducted and classification of polymineral clays of the Republic of Belarus. The ways of intercoupling a structure, phase composition and characteristics of synthesized ceramic material with the initial chemical and mineralogycal composition of clays has been revealled. The influence of temperature and space factors on the change of structure and characteristics of the ceramic material was established, as well as the ways of ceramic masses sintering intensity on the basis of polymineral clays by entering the different additives (including waste of the production) had been developed. The obtained results can be a basis for the choice of the most rational types of clays by its chemical and mineralogical composition, main technological modes when developing and adjusting compositions of masses for ceramic products for different purposes based on local raw materials
