The reactions of synthesis of diopside ceramic pigments using natural minerals - talc and wollastonite are investigated. With a non-stoichiometric ratio of the starting components in two of the three reactions studied, the yield of the main reaction product, diopside, increases, while in the third reaction, a change in the stoichiometry of the incoming components leads to a decrease in the diopside content. It is noted that with a slight deviation from stoichiometry, the dominant crystal structure of the pigment changes, which entails a radical change in its color. Tab. 3, ill. 4, bibliography: 5 titles.
