Precipitation methods of coloured silicates and oxides - highly dispersed pigments

Studies were performed on the production of highly dispersed green pigments, chromium(III) and nickel(II) silicates and oxides in emulsion systems. Appropriately selected parameters in which the process was conducted permitted to obtain pigments of optimum utility properties. The obtained pigments were subjected to a physicochemical analysis, i.a., their principal physicochemical properties were established, the including particle size, particle size distribution and the morphology of the particle surface.
