  • Method for forming ceramic microstructures on a substrate using a mold
    Patent number: 7429345
    Abstract: A microstructured assembly including a barrier portions and land portions is described. The microstructures have alternating barrier portions and land portions that have barrier surfaces and land surfaces, respectively. Each barrier surface and land surface is connected by curved surface, which is part of a curved portion. The curved surface and the land surface are substantially continuous.
    Type: Grant

  • Method for forming microstructures on a substrate using a mold
    Patent number: 7033534
    Abstract: In a method of making a microstructured assembly, a substantially uniform coating of a curable material is formed on a substrate with the coating defining a leading edge. The coating is contacted with a mold starting at the leading edge to form in the curable material a plurality of barrier regions connected by intervening land regions. The curable material is cured and the mold is removed. Optionally, the coating includes a binder. Such a coating can optionally be debinded. In addition, the coating can be fired to form ceramic microstructures.

  • Molding composition containing a debinding catalyst for making ceramic microstructures
    Patent number: 6699927
    Abstract: A molding composition is provided that includes an inorganic component, an organic binder component, and a debinding catalyst. The molding composition is capable of lowering the sintering temperature, for example, when the molding composition is used to make ceramic microstructures such as barrier ribs for plasma display panels.
