Abstract: Disclosed are neutral blue zirconium-vanadium pigments which do not display the disadvantages of previously known generic pigments, namely the high green component and the low color intensity and insufficient reproducibility in the case of neutral blue pigments. The neutral blue pigments with a rather high color intensity and good reproducibility are doped in the host lattice with phosphorus in addition to vanadium and are characterized by their color values in the CIE L*a*b* system. In order to produce such pigments, a zirconium-free mixture of powdery ZrO2, an SiO2 source, a vanadium compound and a phosphorus compound with an atomic ratio of Zr:Si:V:P=1:(0.95-1.10):(0.05-0.20):(0.005-0.03) as well as of a fluoride mineralizer is annealed after intensive grinding at 700 DEG to 900 DEG C.

Abstract: The invention relates to occlusion pigments based on zirconium silicate as the covering substance and chromium(III) oxide as a discretely occluded coloured compound. The occluded Cr2O3 has a D50 value of 0.1 to 3.0 mu m and is a brilliant light green. Compared with non-occluded Cr2O3 having the same D50 value, the pigments according to the invention can be used without trouble for the production of decorations. They are also suitable for direct printing and high-temperature firing-on processes. The pigments are produced by calcining a mixture of zirconium dioxide, silicon dioxide, mineralisers and chromium oxide.

Abstract: Encapsulation pigments comprising chromophoric particles embedded in glaze-stable casings are prepared by means of calcination from the appropriate initial products. High yields and strong color intensities are obtained if the chromophoric substance or its initial compounds are bound in and/or to a zeolite and are calcined in this form with the remaining constituents.
