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: Process for manufacturing mouldings from dealuminised zeolite Y (SiO2/Al2O3 > 20), in which the micropore system of the zeolite and its characteristic adsorption properties are maintained, and in which a binder is used whose suspension in water does not exceed a pH of 10, in amounts between 2 and 40 per cent, based on the mass of zeolite used. … …

Abstract: The invention relates to occlusion pigments based on zirconium silicate as the covering substance and cobalt-free spinels, preferably ZnFe2O4, NiFe2O4 or (Fe,Cr)3O4, as a discretely occluded coloured compound. Preparation is carried out by calcining a mixture of a source of zirconium dioxide, a source of silicon dioxide, mineralisers and cobalt-free oxides in a spinel-forming composition. The pigments are distinguished by their good glaze and colour stability as well as bleeding-out resistance under customary decorative firing conditions.
