Solid-Phase Interactions In Sintered Compositions Based On Quartzite, Quartz Sand And Kaolin

The results of a study of solid-phase interaction in sintered compositions based on quartzite, quartz sand and enriched kaolin are presented. It has been established that the nature of the location of the melting isotherms on the triple diagram indicates the spread of new formation processes into the area of internal compositions of the triangle and the formation of crystalline phases of the minerals α-quartz, tridymite, cristobalite, mullite, which gives the necessary technological properties of finished refractory materials. It is shown that on the basis of quartzite and partially introduced quartz sand in combination with kaolin, it is possible to develop popular compositions of dinas refractory masses for lining non-standard places in high-temperature furnaces.
