Abstract
A product having a glass or glass-ceramic substrate is provided. The substrate is exposable to temperatures in a range of up to 700° C. and has, at least on one surface, a self-cleaning and/or dirt-repellent layer for improving cleanability. The layer is high-temperature resistant, as well as resistant to mechanical stresses. The layer includes at least one of the metal oxides of elements Hf, Y, Zr, or Ce in an at least partially nanocrystalline structure as a basic material, and at least one further metal cation of any of elements Ca, Ce, Y, K, Li, Mg, Sr, and Gd.

1-18. (canceled)
A product comprising:
- a glass or glass-ceramic substrate;
- and
- an inorganic layer at least partially provided on the substrate so that the layer has a surface that forms at least a portion of an outer surface of the product, the layer including a metal oxide and has an at least partially nanocrystalline structure, the layer comprising at least one metal oxide of an element selected from the group consisting of Hf, Y, Zr, and Ce as a basic material, wherein the layer further comprises at least one metal cation of an element selected from the group consisting of Ca, Ce, Y, K, Li, Mg, Sr, and Gd, and, due to the at least one further metal cation, provides a thermo-catalytic function.
A method for producing a product, comprising:
- providing an inorganic layer at least partially on a glass or glass-ceramic substrate, the layer including a metal oxide and has an at least partially nanocrystalline structure, the layer comprising at least one metal oxide of an element selected from the group consisting of Hf, Y, Zr, and Ce as a basic material, wherein the layer further comprises at least one metal cation of an element selected from the group consisting of Ca, Ce, Y, K, Li, Mg, Sr, and Gd, and, due to the at least one further metal cation, provides a thermo-catalytic function.
