A lithium-containing, transparent glass-ceramic material is provided. The material has low thermal expansion and has an amorphous, lithium-depleted, vitreous surface zone. The zone is at least 50 nm thick on all sides and encloses a crystalline interior, which has high transmission. The material includes a transition region connecting the zone and the interior.

Transparent lithium glass-ceramic material, production and use thereof

A transparent glass or glass ceramic pane is provided that includes a glass or glass ceramic substrate having a thermal expansion coefficient &#x3b1; of less than 4.2 and an infrared radiation-reflecting layer, formed as a single-layer reflection layer and having a refractive index greater than 2.2.

Transparent glass or glass ceramic pane with a layer that reflects infrared radiation

A temperature-resistant glass or glass-ceramic pane is provided. The pane includes a substrate and a tin-oxide layer comprising antimony deposited on the substrate.

Glass or glass-ceramic pane reflecting infrared radiation

A transparent, colorless glass or glass-ceramic panel has a visually dense, high-temperature-stable coating having an organic/inorganic network structure containing filling material particles and a color-imparting pigment. The mechanically stable, visually dense coating has no melt-reaction zone at the surface of the panel, which is coated with the coating, so that it does not impair the panel strength. The inorganic network structure can be made from a SiO-based sol. The coating is made by introducing the color-imparting pigment and the filling material particles into a reactive organic/inorganic network structure; applying the resulting organic/inorganic network structure containing the pigment and the filling material particles to the panel to coat the panel and then burning-in the organic/inorganic network structure with the pigment and the filling material particles under thermal conditions to form the coating with no melt-reaction zone.
