GLASS OR GLASS-CERAMIC PRODUCT WITH HIGH TEMPERATURE-STABLE, LOW-ENERGY LAYER

摘要

The invention relates to a product which comprises a substrate made of glass or glass-ceramic, the substrate being exposable to high temperatures in the range up to 700°C and being provided at least on one side with a self-cleaning and/or dirt-repelling layer, for the purpose of enhancing cleanability, this layer being highly heat-resistant and also resistant towards mechanical stresses. The layer of the invention comprises as a base material at least one of the metal oxides of the elements Hf, Y, Zr or Ce, in an at least partly nanocristalline structure, and at least one further metal cation of one of the elements Ca, Ce, Y, K, Li, Mg, Sr or Gd.
