• Resumen

  • The paper presents the results of investigations of the elemental-phase composition and the structure of furnace charge for production of floor and facing tiles at the “Lasselsberger” factory (Ufa). Thermal, electron-microscopical and X-ray investigation of raw materials for the production of ceramic tiles have been performed: clay of the Nizhneuvelsk deposit, kaolin of the Kiembaevsk deposit, kaolin-sand mixture, quartz-feldspar raw material of the Malyshevsk deposit and dolomite of the Balakovo deposit. The processes, occurring in the furnace charge of the facing and floor tiles, with the rise of the burning point were established. On the basis of the obtained data, it was found, that in case of the accelerated factory burning, the same basic structure formation processes occur as in case of the slow burning on the Shimadzu diffractometer: the decomposition of clay minerals, the destruction of carbonates, the synthesis of calcium and mullite silicates, and the formation of glass phase. However, there are some differences in the phase composition and mass content of separate phases. The initial composition of the facing tiles, produced at the factory “Lasselsberger”, was corrected.
