Influence of clay type on the modifying effect of synthetic diopside in ceramic materials

Introduction. In the modern ceramic industry, the composition of the clay charge is adjusted by the introduction of polyfunctional additives, among which silicate fillers on the base of large-tonnage industrial waste are widespread. Synthetic diopside derived from rice husk ash and dolomite, having a number of valuable characteristics, is of undoubted interest as the main crystalline phase in the production of different types of ceramics.

The aim. To investigate the modifying effect of synthetic diopside (SD) derived from rice husk ash (RHA) and dolomite in the composition of ceramic charge based on different types of clay raw materials.

Materials and methods. In this study, there were investigated the clays of Bashkir and Yaush deposits, unmodified compositions based on them, as well as compositions filled with synthetic diopside. Standard experimental methods were used to study the phase and particle size distribution of clays, plasticity, true density and water resistance of base and modified compositions, fire, total and air shrinkage were determined.

Results and discussion. Differences in the phase and particle size distribution of clays do not significantly affect the plasticity of the clay charge, but cause different true density. It was found that water resistance and overall unmodified ceramics based on these clay raw materials differ on average by 10 %.

Conclusions. Synthetic diopside has shown its effectiveness as a modifier of clay raw materials, reducing the shrinkage of ceramic materials and plasticity, with the clay of the Yaush deposit being more promising for application.
