AbstractNew glazes with innovative characteristics have been developed for the ceramic floor and wall tile industry by the dispersion of nanoparticles. Matrix particles of sepiolite clay have been prepared to support and protect different types of dispersed nanoparticles of a metallic or oxide nature. The developed glazes are nanostructured and multifunctional, since different properties can be combined in a single glaze, such as a metallised appearance, and hydrophobic, bactericidal, fungicidal, and self-cleaning properties. The concept of supported nanoparticles uses, efficiently, current processes of nanoparticle technology, providing an innovative ceramic product and greater added value. The developed glaze also addresses issues of great topicality, such as sustainability and the reduction of environmental impact throughout its life cycle, since it requires much smaller quantities of functional metallic oxides and assures their immobilisation thanks to encapsulation. The fact that these metals remain fixed in the sepiolite matrix, avoiding agglomeration and enhancing their stability during the production process, reduces manufacturing costs and minimises occupational risks in the use and handling of nanoparticles.
