  • Publication number: 20080199622
    Abstract: 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 SiO2-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.

  • Patent number: 7413767
    Abstract: A method for producing optical functional coatings comprising niobium, tantalum, titanium or aluminum by supplying a precursor gas of low vapor pressure in a CVD coating system. A precursor selected from the group consisting of Nb, Ta, Ti, and Al compounds having a vapor pressure is maintained within a first supply container at a first temperature T1 and a first pressure p1. Precursor vapor of the precursor is supplied from the first supply container to an intermediate storage device through a first gas line which fluidly communicates the first supply container and the intermediate storage device. A carrier gas or reaction gas is supplied to the first gas line such that a mixture of the precursor with the carrier gas or the reaction gas is provided.

  • Patent number: 7399500
    Abstract: A process for applying alternating layers by chemical vapor deposition comprises the process steps of depositing an adhesion-promoter layer on a substrate and applying a barrier layer. Alternating layers comprising organic and inorganic materials are deposited alternately, and in this process the coating time for application of the adhesion-promoter layer is between 0.05 s and 4.0 s and the coating time for application of the inorganic barrier layer is between 0.1 s and 6.0 s. A composite material is also produced using the process.
