摘要:
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.
摘要:
A method for producing a pane of a household appliance or a viewing window of an oven is provided. The method includes the steps of: providing a substrate; applying a sol-gel layer to the substrate; embossing a haptically perceptible pattern using an embossing tool in the sol-gel layer; and curing the sol-gel layer. A pane of a household appliance or piece of furniture is also provided that includes a glass or glass-ceramic substrate with a patterned sol-gel layer which has a haptically perceptible pattern.
摘要:
A semi-transparent coating material for coating glass or glass ceramics includes at least one sol-gel hybrid-polymer coating system having a hybrid-polymer or inorganic sol-gel-based matrix, and nanoparticles and nanoscale pigments and/or dyes are added to the hybrid-polymer or inorganic sol-gel-based matrix.
摘要:
The invention relates to a method for producing a glass or glass-ceramic article, comprising a decorative layer and a sealing layer. The two layers are produced by means of a sol-gel process and contain, in addition, at least fillers and inorganic pigments, wherein it is possible for the pigmentation of the decorative layer and the sealing layer to be the same or else different. In order to achieve a good adhesive strength and impermeability of the decorative coating, certain composition rules in regard to the quantity and kind of inorganic pigments used must be observed and, surprisingly, are different for the sealing layer according to the invention than for the decorative layer. The invention relates, furthermore, to a glass or glass-ceramic article with decorative coatings, produced particularly according to the method of the invention, said article being suitable especially for use as glass-ceramic cooktops.
摘要:
A display device is provided that is a transparent, colored glass-ceramic with a display face on the front, an illumination face on the back, and at least one light-emitting element being disposed in the region of the illumination face. The display device further includes a color compensation filter in the form of a color layer introduced directly or indirectly on the glass ceramics.

A semi-transparent coating material for coating glass or glass ceramics includes at least one sol-gel hybrid-polymer coating system having a hybrid-polymer or inorganic sol-gel-based matrix, and nanoparticles and nanoscale pigments and/or dyes are added to the hybrid-polymer or inorganic sol-gel-based matrix.
摘要:
The invention relates to the production and use of a gray hue palette for decorative coatings based on a sol-gel method for glass and glass-ceramic articles, wherein flake-form pigments and solid lubricant are used in specific mass ratios as decorative pigments. The pigmentation provides a high-temperature-stable decorative layer, has good adhesive strength between the substrate and the decorative layer, has good impermeability relative to fluids and gases during use, as well as a high resistance to scratching. The invention further relates to glass or glass-ceramic articles with decorative coatings which are produced, in particular, according to the method of the invention, which are suitable particularly for use as glass-ceramic cooktops due to the named good layer properties of the decorative layer.
摘要:
A coating material is provided that includes a sol-gel coating system, pigments, and chain-like or fibrous nanoparticles. The coating system is stable at high temperatures and is suitable for glass or glass-ceramic substrates having a low thermal expansion coefficient.

摘要:
In order to provide a decorative coating (9) which exhibits improved temperature resistance and strength on glass and glass-ceramic and which also has no strength-reducing effect on the substrate (3), or at least no longer has any substantially strength-reducing effect on the substrate, the invention envisions a process for producing glass or glass-ceramic articles having a decorative layer in which at least one decorative pigment (13) is mixed with a sol-gel binder (11), and the pigment mixed with the sol-gel binder is cured on the glass or glass-ceramic substrate of the article by annealing, to form a decorative layer having a porous ceramiclike structure.
