  • Free flowing powder and process for producing it
    Patent number: 4028095
    Abstract: Free flowing powders, such as for flame spray applications, are produced by spray drying a slurry of finely divided particles of the metal in a solvent-binder system to produce agglomerates, wherein the binder is a soluble compound of the metal. These agglomerates possess sufficient green strength to be screened and exhibit higher apparent densities than comparable powders agglomerated with conventional organic binders. When these powders are heated in a reducing atmosphere above the decomposition temperature of the binder, the binder converts to base metal and harmless by-products, such as nitrogen and water thus avoiding contamination of the product, equipment and work area usually associated with conventional organic binders.
    Type: Grant
    Filed: March 31, 1976
    Date of Patent: June 7, 1977
    Assignee: GTE Sylvania Incorporated
    Inventors: John M. Laferty, Jr., Joseph E. Ritsko, David J. Port
