  • Method of forming sodium beta-Al.sub.2 O.sub.3 films and coatings
    Patent number: 4244986
    Abstract: A sodium Beta-alumina thin film is coated onto a supporting substrate by forming an agglomerate-free, hydrolyzed sol, principally comprising an electrically surface active polymer formed by the hydrolysis and peptization of sodium and aluminum alkoxides, which is applied to the substrate. The substrate and applied sol are then heated to crystallize the polymer and form a solid film having pores with radii of up to about 250 Angstrom units.
    Type: Grant
    Filed: April 24, 1979
    Date of Patent: January 13, 1981
    Assignee: Westinghouse Electric Corp.
    Inventors: Deborah M. Paruso, Bulent E. Yoldas
  • Method of forming sodium beta-Al.sub.2 O.sub.3 solid materials
    Patent number: 4208475
    Abstract: A liquid polymer is formed in a low temperature polymerization reaction involving organo-metallic sodium and aluminum compounds, at least one of which is partially hydrolyzed. The polymer is hydrolyzed, dried to form an amorphous sodium Beta-alumina precursor, and then heated, at between 1,200.degree. C. and about 1,550.degree. C., to form a ceramic, comprising ion-conductive sodium Beta-alumina which is useful as a solid electrolyte.
