Kaolins for production of sanitary ceramics

Several types of kaolins from different manufacturers were investigated. The chemical, mineral, and granulometric compositions of the kaolins and their effect on the properties of the finished pastes were investigated. The properties of kaolins required for optimizing the properties of ceramic pastes were determined. The rheological characteristics were examined and their effect on control of the manufacturing process were examined. The basic drawbacks and advantages of the different types of kaolins, both those traditionally used by domestic manufacturers and some new ones, were established.
