  • Patent number: 10259955
    Abstract: Pigments and inks for the decoration of ceramic objects, which have, in their formulation, iron and phosphorus oxides, combined with lithium oxide, the presence of this latter element being that which gives the pigments the capacity of being milled (in the form of a suspension in a solvent base) to the point of being able to obtain inks that are characterized by having very narrow PSD and an upper bound of less than 1 ?m. Thanks to this PSD, inks prepared using these pigments can be applied in standard printing heads to glazed ceramic objects, enabling a metallic gloss and appearance to be obtained after said ceramic objects undergo a firing process. The ink obtain has a low viscosity, allowing an increase in the concentration of the pigment and thus an increase in its yield, optimizing gloss and the metallic appearance of the finished ceramic objects.
