  • Tantalum powder and method of making same
    Patent number: 5261942
    Abstract: An improved flaked tantalum powder and process for making the flaked powder are disclosed. The powder is characterized by having a Scott density greater than about 18 g/in.sup.3 and preferably at least about 90% of the flake particles having no dimension greater than about 55 micrometers. Agglomerates of the flaked tantalum powder, provide improved flowability, green strength and pressing characteristics compared to conventional flaked tantalum powders. The improved flaked tantalum powder can be made by preparing a flaked tantalum and then reducing the flake size until a Scott density greater than about 18 g/in.sup.3 is achieved. The invention also provides pellets and capacitors prepared from the abovedescribed flaked tantalum powder.
    Type: Grant
    Filed: March 10, 1992
    Date of Patent: November 16, 1993
    Assignee: Cabot Corporation
    Inventors: James A. Fife, Marlyn F. Getz

  • Method for improving handling properties of a flaked tantalum powder composition
    Patent number: 4555268
    Abstract: A method for improving the handling characteristics of a flaked tantalum powder composition comprising heat treating the flaked powder component of the composition in order to pre-agglomerate the flaked component prior to mixing it with the granular tantalum powder component of the composition.
