  • Method for producing sintered lithium oxide granules
    Patent number: 5676919
    Abstract: High-purity, sintered spherical Li.sub.2 O granules is produced by a gel precipitation technique. Li.sub.2 CO.sub.3 powder is dispersed in an aqueous solution of a water-soluble resin, whose drops are transferred through a nozzle into a solidifying acetone bath. Spherical gel particles in which Li.sub.2 CO.sub.3 is dispersed are formed in the acetone bath. The spherical gel particles are dried, calcined, thermally decomposed and sintered.
