COLORING OF CERAMIC, BASED ON ZIRCONIUM DIOXIDE Russian patent published in 2017 - IPC C04B41/85 A61K6/27 

FIELD: medicine.

SUBSTANCE: present invention relates to set of components, containing coloring solution, porous preliminary sintered product, based on zirconium dioxide, optional equipment for application, and is used for making dental ceramic products: crowns, onlays, veneers, etc. Coloring solution in set contains cation(s) of coloring agent(s), selected from Fe, Mn ions, Er, Pr, V, Cr, Co, Mo, Ce, Tb and mixtures thereof, in amount of more than approximately 0.05 mol/l, solvent(s) for ion(s), optional complexing agent(s), optional thickener(s), optional organic marking substance(s), optionally additive(s), wherein porous product, based on zirconium dioxide shows isotherm type IV absorption and/or desorption N2 in compliance with classification of IUPAC. Method of coloring products, based on zirconium dioxide, involves stages, on which coloring solution is applied on at least part of porous product, based on zirconium dioxide, optionally dried and sintered to produce colored ceramic product, based on zirconium dioxide.

EFFECT: technical result of invention is possibility to produce individually colored dental ceramics with controlled light transmission.
