  • Publication number: 20160218269
    Abstract: The films of this invention are high temperature superconducting (HTS) thin films specifically optimized for microwave and RF applications. In particular, this invention focuses on compositions with a significant deviation from the 1:2:3 stoichiometry in order to create the films optimized for microwave/RF applications. The RF/microwave HTS applications require the HTS thin films to have superior microwave properties, specifically low surface resistance, Rs, and highly linear surface reactance, Xs, i.e. high JIMD. As such, the invention is characterized in terms of its physical composition, surface morphology, superconducting properties, and performance characteristics of microwave circuits made from these films.
    Type: Application

  • Patent number: 4017425
    Abstract: A method for activating the red mud formed in the Bayer alumina producing process for allowing its use as adsorbent, catalyst, ion-exchanging substance and clarifying substance, comprising a digesting red mud and dispersing the metal oxide compound particles in the compound of metal hydroxides and silica gel. The method comprises digesting red mud with acid, before adjusting the pH of the acid digested mixture comprising the sludge product to above 4 to disperse oxide compound in the compound the metal hydroxides and silica gel, and removing the residue acid employed from the gelating product with washing, then with or without shaping treating, and heat treating the product to provide a active red mud, particularly with respect to the catalytic cracking, decolorization of hydrocarbon, clarification of waste gas and adsorption processes.
