FIELD: varnish-and-paint industry.
SUBSTANCE: invention is designed for use in construction and chemical industry when dyeing building materials and parts, manufacturing enamels, glazes, ceramic paints, and polymer fillers. Pyroxene mineral (diopside or vollastonite) is brought into interaction in solution with salt colored by iron triad element cation (iron, cobalt, or nickel molybdophosphate) synthesized and crystallized directly in solution at 30-60°C. Interaction and precipitation of the salt on the surface of pyroxene mineral is effected during 15-30 min. Thus obtained precipitate is filtered and dried. Inorganic pigment 50-90% pyroxene mineral and 10-50% molybdophosphate. Color spectrum of pigments extends from lilac to brown depending on nature and quantity of chromophore.
EFFECT: increased coloration intensity and color purity.
