US 11,780,785 B2 · Ceramic coatings with apatite carbonate that allow a tactile thermal sensation similar to wood and good resistance against wear, chemical attack and staining

Abstract

In one aspect, the present invention comprises providing an additive or aggregate to be applied directly to one or more of the components of a ceramic coating and which is constituted by carbonate apatites particles which are maintained as aggregates within a matrix of silicoaluminates at firing temperatures of the ceramic coatings, where the main function of these aggregates is to provide the ceramic coating properties selected from the group comprising: low effusivity, wear resistance, resistance to chemical attack and resistance to staining. In other aspects, the present invention comprises providing a ceramic coating incorporating said additive and a method for providing a ceramic coating with properties selected from the group comprising: low effusivity, wear resistance, resistance to chemical attack and resistance to staining.

Dependent claims

A ceramic coating comprising a ceramic support body and the following layers:

a layer called enamel comprising a glass layer;
and a layer called engobe which allows union between the enamel and the ceramic support body, wherein the ceramic coating is characterized by at least one of its layers containing from 0.50% to 30% by weight of an additive comprising carbonate apatites which have in its structure carbonates (CO3) that partially replace groups PO43- in a 0.1% to 8.0% by weight;
wherein carbonate apatites are selected from one or more materials of the group consisting of:
natural carbonate apatites, synthetic carbonate apatites, or mixtures thereof and wherein the carbonate apatites are in the form of particles comprising diameters between 100 nanometers and 50 microns.
