Production of ceramic pigments with wollastonite and diopside structures using nepheline sludge
- 39 Downloads
Ceramic pigments with wollastonite and diopside structures were obtained by using nepheline sludge in charge adjustment with magnesium and silicon oxides. The pigments are resistant to high temperatures and the effect of fluxes and glazes. They can be recommended to complement pigments of spectral colors and for bulk coloring of ceramic pastes and glazes. In addition to lowering the price of the pigments, problems of using nonutilizable production wastes are solved and the raw-material base for synthesis of ceramic pigments is expanded.
