Abstract

See full text

The invention relates to kit of parts comprising a solution, a porous zirconia article, optionally application equipment, the solution comprising cation(s) of non-coloring agent(s) selected from ions of Y, Gd, La, Yb, Tm, Mg, Ca and mixtures thereof, solvent(s) for the ion(s), optionally complexing agent(s), optionally thickening agent(s), optionally organic marker substance(s), optionally additive(s), the porous zirconia article showing a N2 adsorption and/or desorption of isotherm type IV according to IUPAC classification. The invention also relates to a method for enhancing the translucency of a zirconia article comprising the steps of providing a porous zirconia article and a solution, applying the solution to at least a part of the outer surface of the porous zirconia article, optionally drying the porous zirconia article of the preceding step, sintering the porous zirconia article to obtain a zirconia ceramic article.
