  • Patent number: 6863750
    Abstract: High purity niobium metals and alloys containing the same are described. The niobium metal preferably has a purity of at least 99.99% and more preferably at least 99.999%. In addition, niobium metal and alloys thereof are described, which either have a grain size of about 150 microns or less, or a texture in which a (100) intensity within any 5% increment of thickness is less than about 30 random, or an incremental log ratio of (111):(100) intensity of greater than about ?4.0, or any combination of these properties. Also described are articles and components made from the niobium metal which include, but are not limited to, sputtering targets, capacitor cans, resistive film layers, wire, and the like. Also disclosed is a process for making the high purity niobium metal which includes the step of reacting a salt-containing niobium and a metal salt along with at least one compound capable of reducing the salt-containing niobium to niobium and in a reaction container.

  • Patent number: 6576069
    Abstract: An alloy comprising tantalum and silicon is described. The tantalum is the predominant metal present. The alloy also has a uniformity of tensile strength when formed into a wire, such that the maximum population standard deviation of tensile strength for the wire is about 3 KSI for an unannealed wire at finish diameter and about 2 KSI for an annealed wire at finish diameter. Also described is a process of making a Ta-Si alloy which includes reducing a silicon-containing solid and a tantalum-containing solid into a liquid state and mixing the liquids to form a liquid blend and forming a solid alloy from the liquid blend. Another process of making a Ta-Si alloy is described which involves blending powders containing tantalum or an oxide thereof with powders containing silicon or a silicon-containing compound to form a blend and then reducing the blend to a liquid state and forming a solid alloy from the liquid state.

  • Patent number: 4526749
    Abstract: Disclosed is a novel refractory metal alloy that retains the essential characteristics of pure tantalum and, additionally, has improved engineering characteristics and may be produced at a lower cost than pure tantalum. The alloy nominally contains, by weight, about 58% tantalum, about 2.0% molybdenum, about 2.5% tungsten and about 37.5% columbium.
