  • Patent number: 8039130
    Abstract: Heat treatment is conducted at a predetermined temperature of not less than 1250° C. on an underlying substrate obtained by epitaxially forming a first group-III nitride crystal on a predetermined base as an underlying layer. Three-dimensional fine irregularities resulting from crystalline islands are created on the surface of the underlying layer. A second group-III nitride crystal is epitaxially formed on the underlying substrate as a crystal layer. There are a great many fine voids interposed at the interface between the crystal layer and underlying substrate. The presence of such voids suppresses propagation of dislocations from the underlying substrate, which reduces the dislocation density in the crystal layer. As a result, the crystal layer of good crystal quality can be obtained.

  • Patent number: 8017243
    Abstract: An absorbing layer of a low-E coating is designed to cause the coating to have a more neutral and/or green color at normal and/or certain off-axis viewing angles. In certain example embodiments, the metallic or substantially metallic absorbing layer (e.g., NiCr) is from about 20-30 angstroms (?) thick; this thickness has been found to unexpectedly provide less red and more neutral coloration for the coated article at certain off-axis viewing angles (e.g., at a 45 degree off-axis viewing angle). In certain example embodiments, the absorbing layer is provided between first and second nitride layers in order to reduce or prevent oxidation thereof during heat treatment thereby permitting predictable coloration to be achieved following the heat treatment. Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, vehicle windows, other types of windows, or in any other suitable application.

  • Patent number: 8016967
    Abstract: In the manufacture of a multilayer ceramic substrate including a ceramic laminate by a so-called non-shrink process in which the ceramic laminate disposed between shrinkage control layers is fired, first and second surface conductive films formed on first and second main surfaces of the ceramic laminate may cause warping of the multilayer ceramic substrate after the shrinkage control layers are removed. After the firing step, in removing the shrinkage control layers from a composite laminate, the thickness of at least one of first and second reaction layers formed at interfaces between ceramic green layers and the shrinkage control layers in the firing step is reduced such that the thickness of the first reaction layer is different from the thickness of the second reaction layer, thereby controlling the compressive stress generated by the reaction layers to reduce the warping of the multilayer ceramic substrate.

  • Patent number: 7998601
    Abstract: A method produces thermal barrier coatings that adhere to components even at high temperatures and temperatures that change frequently. A gas-tight glass-metal composite coating is applied to the component and annealed. The corroded part of the gas-tight coating is then removed, and a second, porous coating is applied. The second coating can comprise a ceramic, in particular yttrium-stabilized zirconium oxide. A thermal barrier coating is provided that is a composite made of a gas-tight glass-metal composite coating and another porous coating disposed thereover. Because the boundary volume of the composite coating is partly crystallized to the other coating, superior adhesion within the composite is achieved. Thus, it is in particular possible to produce a composite made of silicate glass-metal composite coatings and yttrium-stabilized zirconium oxide that are temperature-stable for extended periods of time.
