  • Publication number: 20070193026
    Abstract: This invention is directed to a method of forming electrical conductors comprised of conductive metals generally carried on a substrate. In the method, a conductor formulation generally comprised of metal particles or metal precursor or mixture thereof, typically in the form of an ink or paste, is applied to the substrate and converted into a conductive metal by application of sufficient heat and for a sufficient time to effect sintering thereof while in the presence of a negatively charged ionic reducing gas.

  • Patent number: 7201018
    Abstract: The invention relates to a process and apparatus for delivering an ultra high purity fluid comprising at least one component to a point of use at a required pressure without mechanical pumping. In one embodiment, a high purity feed comprising at least one component in gaseous or liquid form is charged into a vessel and at least partially converted to a solid phase source. As the feed is converted to a solid phase source, additional feed may be added until the vessel is at least substantially filled with a solid phase source or slush. Once filled, the solid phase source or slush may be isochorically heated whereby the solid phase source is converted to a product at an elevated pressure.

  • Publication number: 20040154333
    Abstract: This invention relates to a process and apparatus for delivering an ultra high purity fluid comprising at least one component to a point of use at a required pressure without pumping. In one embodiment, a high purity feed comprising at least one component in gaseous or liquid form is charged into a vessel and at least partially solidified, i.e., converted to a solid phase source. As the feed is converted to a solid phase source, additional feed may be added until the vessel is at least substantially filled with a solid phase source or slush. Once filled, the solid phase source or slush may be isochorically heated whereby the solid phase source is converted to a product at an elevated pressure. In other embodiments, an apparatus and a method for the production and collection of a high purity solid phase source or slush comprising at least component is disclosed herein.
