HIGH-TEMPERATURE PHASE TRANSFORMATIONS IN THE COMPOSITION “KAOLIN-DOLOMITE-ALUMINA”

The article presents the results of a study of phase transformations in sintered compositions “kaolin-dolomite-alumina”. It has been established that the nature of the location of melting isotherms on the triple diagram indicates the spread of neoformation processes into the region of the internal compositions of the triangle and the formation of crystalline phases of the mineral’s spinel, corundum, mullite. It is shown that based on alumina-containing waste and kaolin, as well as partially introduced dolomite, it is possible to develop compositions of low-temperature sintering ceramic masses for technical materials.
