Abstract

This paper examines the peculiarities of the phase composition of black clinker bricks based on the ceramic masses of Kerameya enterprise (Sumy, Ukraine). The principles of charge choice are given considering the ratio of coloring oxides Fe2O3, CoO, MnO2, Mn3O4 and CuO. We found that the phase composition of black clinker bricks after firing at 1100 °С is mainly represented by quartz, microcline, mullite, residues of biotite, as well as hematite and hausmannite as the coloring phases, and also small amounts of cuprite. To produce black ceramic bricks on the basis of clay composition, we need to take 13.5 wt% elements with the ratio of Mn: Fe: Ti: Cu equal to 4.2: 7.7: 0.5: 1.1. Such ceramic mass is already used to produce ceramic clinker bricks with water absorption of 5%, mechanical compressive strength of more than 35 MPa and frost resistance of more than 150 freezing and thawing cycles.
