Abstract: 
The effect of the mineralogical form and chemical composition of siliceous and calcareous components on the physicochemical processes of calcium silicate and hydrosilicate formation has been investigated under two-stage wollastonite synthesis conditions. It was established that the degree of SiO2 crystallinity and the presence of foreign impurities in the raw materials have a decisive influence on the formation of the tobermorite phase during hydrothermal treatment. The patterns of microstructure formation of the synthesized products have been studied. It has been shown that amorphous varieties of silica form more crystallized calcium hydrosilicates than quartz. Using XRD and SEM methods, it has been established that the transformation of tobermorite into β-wollastonite occurs within the temperature range of 900–1100 °C. As the burning temperature increases, the degree of wollastonite crystallinity and crystal sizes increase. The optimum temperature for obtaining β-wollastonite with a distinct columnar morphology and crystal sizes of 2–5 μm is 1100 °C. The proposed technology enables the synthesis of wollastonite with controlled structural characteristics at lower temperatures compared to classical methods of solid-phase synthesis. It also allows for reduced energy costs and the use of available secondary raw materials.
