  • Patent number: 6030681
    Abstract: A method of forming an article having a cermet layer on a porcelain substrate, via the steps of (a) providing a substrate made a porcelain comprising one or more crystalline oxide phases dispersed in a glassy matrix, the glassy matrix containing 0.25 to 45.0 weight % of a reducible metal oxide having a reduction potential of between -1.0 and +3.5 E.degree./V; and (b) heating the substrate in a reducing atmosphere to form on at least one surface of the substrate a layer of cermet comprising elemental metal which is a reduction product of the reducible metal oxide. The article may be used as a substrate for magnetic recording disks.

  • Patent number: 5720859
    Abstract: An electrode is formed on a substrate such as a varistor, a PTC ceramic, or a piezoelectric ceramic by coating a surface of the substrate with a combination of a metal source and a source of reducing carbon. The substrate and/or the combination is an absorber of microwave radiation. Irradiation with microwave radiation causes a carbothermic reduction to occur, converting the metal source to a metal electrode on the substrate.
