    Abstract: A superior braze material, along with a method of producing the braze material and a method of sealing, joining or bonding materials through brazing is disclosed. The braze material is based on a metal oxide-noble metal mixture, typically Ag—CuO, with the addition of a small amount of metal oxide and/or metal such as TiO2, Al2O3, YSZ, Al, and Pd that will further improve wettability and joint strength. Braze filer materials, typically either in the form of paste or thin foil, may be prepared by a high-energy cryogenic ball milling process. This process allows the braze material to form at a finer size, thereby allowing more evenly dispersed braze particles in the resultant braze layer between on the surface of the ceramic substrate and metallic parts.

Further, the heights of the solder balls and the upper surface of the mask are made equal by using the spacer, making it possible to securely load the solder balls on the electrode pads, one solder ball for each connection pad, and to reduce a probability that solder balls are not loaded or that a plurality of the solder balls are loaded onto a single connection pad.

    Abstract: A method for sealing the curved vacuum glass comprises: first preparing metallized layer bonded with the glass plate on the edge surface of the curved glass to be sealed by locally heating the metal slurry coating; then air-tightly sealing the edges of two glass plates by using the metal brazing technology, or air-tightly sealing the edges of two glass plates by air-tightly welding the metal sealing sheet between the metallized layers of two glass plates to be sealed. A curved vacuum glass is also provided. The method makes the sealing part have firm connection, good air tightness and good thermal shock resistance. The sealing structure made of the metal sealing sheet is well compatible with the temperature deformation caused by the temperature difference between the internal and external glass plates of the vacuum glass.

  • Publication number: 20120177488
    Abstract: A process for joining silicon-containing ceramic articles, and particularly ceramic articles and CMC articles that contain both silicon carbide and free silicon. The process entails providing a reactive metal-containing braze material between the articles, and then heating the braze material and the articles to react the reactive metal with the silicon within the articles to form a brazement containing a silicide phase of the reactive metal. The brazement and articles are then cooled to produce a component comprising the two articles and the silicide phase-containing brazement. The process is preferably carried out at temperatures below that which would thermally degrade constituents of the articles, and more preferably below the melting point of silicon.
