Abstract

Annotation. The aim of research is the production of ceramic wall roasting at lower temperatures due to the modification of the activated aluminosilicate raw Na-Fe-containing compounds. Research methods. Theoretical studies were conducted on the basis of the analysis and systematization of scientific ideas about the mechanism of the physico-chemical aspects of formation of structure of wall ceramics. Experimental studies were carried out using mathematical methods of experimental design. Research phase composition and microstructure of materials were carried out using a complex instrumental methods of physical and chemical analysis: X-ray diffraction, differential-thermal, dilatometric, electron microscopy. Physical and mechanical properties of the materials were investigated using standard methods in accordance with existing regulations. Scientific novelty of the results is to establish patterns of producing composite low-temperature wall ceramics by modifying the activated aluminosilicate raw Na-Fecontaining compounds. Ceramic wall is designed with low-temperature sintering raw material partially activated aluminosilicate modified Na-Fe-containing compounds. Modifying components are placed between the aluminosilicate dispersions during firing react with oxides on the surface of the dispersion to form a low-melting eutectic in the contact zones. On cooling the contact zones are formed compounds which bind aluminosilicate dispersion monolith. The formation of low-melting eutectics contact zones reduces raw baking temperature 950-970 to 850-870 ° C. The practical significance of the results is the development of formulations and technology solutions for low temperature burning wall ceramics.
