  • Publication number: 20140084503
    Abstract: A flame spray pyrolysis method for making nanoscale, lithium ion-conductive ceramic powders comprises providing a precursor solution comprising chemical precursors dissolved in an organic solvent, and spraying the precursor solution into an oxidizing flame to form a nanoscale, lithium ion-conductive ceramic powder, wherein a concentration of the chemical precursors in the solvent ranges from 1 to 20 M. The precursor solution can comprise 1-20% excess lithium with respect to a stoichiometric composition of the ceramic powder. Nominal compositions of the nanoscale, ceramic powders are Li1.4Al0.4M1.6(PO4)3 where M is Ti or Ge.

  • Patent number: 8574670
    Abstract: A method and apparatus for applying a uniform membrane coating to a substrate, such as a honeycomb structure, having a plurality of through-channels, wherein the through-channels have an average diameter of less than or equal to 3 mm. The method includes providing a liquid precursor comprising membrane-forming materials to the substrate and applying a pressure differential across the substrate. The pressure differential causes the liquid precursor to travel uniformly through the through-channels, depositing the membrane-forming materials on the walls of the through-channels and forming the membrane on the walls of the through-channels. The apparatus includes a chamber capable of holding the substrate and of maintaining a pressure differential across the plurality of through-channels.

  • Publication number: 20130122196
    Abstract: A coating apparatus includes modular interfaces and substrate receptors for accommodating various shapes and sizes of monolith substrates when coating layers are applied onto the monolith substrates. The monolith substrates are laterally surrounded by an elastically deformable sleeve that prevents lateral leakage of a vacuum out of the monolith substrate when a vacuum is applied to opposing ends of the monolith substrate, thereby eliminating needs for bulky vacuum chambers. The coating apparatus also includes valves and control apparatus that enable excess precursor liquid to be drained from monolith channels in-situ, without the use of additional spin-drying steps. Coating methods for using the coating apparatus are provided.
