Production of ceramic pigments having a structure of wollastonite and diopside using nepheline slip

Ceramic pigments with wollastonite and diopside structures were obtained using nepheline sludge with magnesium and silicon oxides. Pigments are resistant to high temperatures, the action of melted fluxes and glazes. They can be recommended in addition to spectral color pigments, as well as for volumetric coloring of ceramics and glazes. In addition to reducing the cost of pigments, the tasks of using waste production waste are being solved, as well as expanding the raw material base for the synthesis of ceramic pigments.
