The sintering peculiarities of the ceramic materials which had been prepared by means of semidry pressing are investigated in the article. The fillers were the yttrium oxide Y2O3 and the fused corundum α-Al2O3, the bonding phase was the aluminoxane addition either pure or modified by the yttrium and magnesium compounds. We investigated the processes occurring at the examined ceramics sintering at different temperatures and their influence on the obtained ceramics properties. The phase composition, the thermal and mechanical properties of the test samples at 1500 °C are presented. The produced test ceramic crucibles have advanced thermal resistance and stability against the thermal cycling. The possibility is regarded to use the developed ceramic crucibles for melting and casting of the chemically reactive highly-heat-resistant metals and alloys.

Technogenic Wastes

The article provides information on industrial waste generation at enterprises of the Samara region, suitable for use as raw materials components of such heat-resistant composites as solutions, concretes, gun mixes, coatings. The research indicates rational ways of some heat-resistant binders application for utilization of mineral high-melting and heat-resistant industrial wastes. It proves that the enrichment of certain types of industrial waste, i.e. bringing the chemical composition of their components to the required state, allowed to expand the raw material base for the synthesis of heat-resistant binders and concrete in general. The use of sludge waste in the processes of synthesizing liquid phosphate binders allowed to obtain such effective binders as aluminophosphates and aluminocalciumphosphates. The research proves that application of technogenic wastes of non-ferrous metallurgy enterprises allows to receive heat-resistant materials solutions, concretes, coatings, gun mixes which characteristics are similar to their industrial analogues.

The article describes various methods of synthesizing heat-resistant binders based on large-tonnage wastes of enterprises. The use of pyrite butts and expanded clay dust, respectively, from the Chapayevsky Chemical Plant and the expanded clay plant of the city of Samara in the compositions of heat-resistant concrete on phosphate binders allowed to increase their residual strength in the zone of critical temperatures (1300-1350 °С). The refractoriness of these phosphate binders turned out to be very low (≈1300 °С), which required the use of such a method of its increase as the introduction of fine high-alumina fillers with high melting points into the composition of the binder. It was revealed and justified that the use of an alumina-chromium petrochemical waste IM-2201 allowed to increase the refractoriness of the heat-resistant composition to 1600 °С. On the basis of the developed alumina-iron-phosphate, zirconyliron- phosphate and alumino-silicophosphate binders, the compositions of heavy concrete with chamotte and high-aluminous aggregates of grades 400 and 500 were selected.
