The possibility of ceramogranite production from quartz-feldspar raw of Ukraine

The results of research on the use of quartz-feldspar rocks of Ukraine (granites and pegmatites) as fluids in the production technology of stone-ceramic products are presented. A theoretical assessment of the fluxing ability of rocks is carried out, and a justification is given for the need to use additives in the mass compositions that reduce the viscosity of melts. The influence of the type and amount of fluids and additives on water absorption, fire shrinkage of specimens and their tendency to deformation has been investigated. The areas of optimal compositions of the masses, on the basis of which ceramic materials with the properties of porcelain stoneware are obtained, have been established.
