  • Fine grained embrittlement resistant tantalum wire
    Patent number: 4859257
    Abstract: Tantalum and tantalum-based alloys, particularly in wire form, are significantly improved in retention of a fine grain size at elevated temperatures and in resistance to embrittlement by the addition of 10 to 1000 ppm silicon and 10 to 1000 ppm thorium-containing material.
    Type: Grant

    Date of Patent: August 22, 1989
    Assignee: Fansteel Inc.
    Inventors: Victor T. Bates, Charles Pokross
  • In situ phosphorus addition to tantalum
    Patent number: 4356028
    Abstract: During the method of preparing tantalum powder from a tantalum rich solution in an organic solvent in which a tantalum salt is precipitated from the tantalum rich solvent and the tantalum salt is reduced to metalic tantalum by an alkali metal, a phosphorus-containing material is added to either the precipitated step or the reduction step or both.
