  • Patent number: 11649537
    Abstract: Provided are Ce/Co/Cu permanent magnet alloys containing certain refractory metals, such as Ta and/or Hf, and optionally Fe which represent economically more favorable alternative to Sm-based magnets with respect to both material and processing costs and which retain and/or improve magnetic characteristics useful for GAP MAGNET applications.
    Type: Grant
    Filed: December 10, 2018
    Date of Patent: May 16, 2023
    Assignee: Iowa State University Research Foundation, Inc.

  • Publication number: 20220340438
    Abstract: A method of selectively extracting lithium from a lithium sulfate aqueous solution, the method comprising: (i) mixing an aluminum-containing sorbent material into the lithium sulfate aqueous solution to form a precursor mixture, wherein the aluminum-containing sorbent material is an aluminum hydroxide, aluminum oxide, or combination thereof; and (ii) heating the precursor mixture to a temperature of 50-200° C. to result in selective formation of a solid lithium-aluminum complex and mother liquor; and wherein the method may further comprise: (iii) recovering isolated lithium salt from the solid lithium-aluminum complex by heating the solid lithium-aluminum complex in water or aqueous solution at a temperature of 50-100° C. to result in delithiation of the solid lithium-aluminum complex with transfer of the lithium salt from the solid lithium-aluminum complex to the water or aqueous solution, along with production of aluminum hydroxide solid.
