Abstract

The results of the study of the physicochemical properties of the modified saponite isolated from the recycled water of the enrichment plant of Severalmaz JSC showed that the process of intercalation of cations of different nature into its structure changes the electrical conductivity of the samples, which makes it possible to control the residual moisture content of the material. In addition, changing the nature of the cations introduced into the interpackage distance of the saponite makes it possible to minimize the firing shrinkage of the raw saponite in the manufacture of ceramic products. Singly charged ( \({\text{NH}}_{4}^{ + },\) Na+), doubly charged (Mg2+, Ca2+), and triply charged (Fe3+) ions were used as intercalated cations. It has been established that the electrical resistance for all the studied samples increases according to a power function as moisture is removed, and the shrinkage of the saponite-containing raw material, depending on the introduced cation, can be reduced by 30 to 40%.
