  • Method for improving quality of triniobium tin superconductor in manufacturing environment by controlling iron content in molten tin bath
    Patent number: 6358331
    Abstract: A tin alloy bath with controlled iron content is used for coating a niobium-base substrate with tin in a manufacturing process for triniobium tin superconductor. One hundred twenty-five parts per million by weight or less of iron is used in tin alloy baths to increase the reaction kinetics of the formation of the superconductor material.

  • Nb--Sn precursors having controlled impurities and method of making
    Patent number: 5670204
    Abstract: Nb--Sn precursor articles are described that include a Nb alloy article that is at least partially coated with a layer of a Sn alloy, such as a Sn--Cu alloy. The precursor articles described herein have a controlled concentration of the impurity elements As and S in the Sn alloy layer. The concentration of these elements in the Sn alloy layer is less than or equal to 50 ppm by weight. This invention also describes a method for making Nb--Sn precursor articles having a controlled concentration of As and S impurities.
