    摘要： High purity tantalum metals and alloys containing the same are described. The tantalum metal preferably has a purity of at least 99.995 % and more preferably at least 99.999 %. In addition, tantalum metal and alloys thereof are described, which either have a grain size of about 50 microns or less, or a texture in which a (100) intensity within any 5 % increment of thickness is less than about 15 random, or an incremental log ratio of (111):(100) intensity of greater than about -4.0, or any combination of these properties. Also decribed are articles and components made from the tantalum 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 metal which includes the step of reacting a salt-containing tantalum with at least one compound capable of reducing this salt to tantalum powder and a second salt in a reaction container. The reaction container or liner in the reaction container and the agitator or liner on the agitator are made from a metal material having the same of higher vapor pressure of melted tantalum. The high purity tantalum preferably has a fine and uniform microstructure.

    摘要： Polymer compositions, which are particularly useful in automotive applications, are described. The polymer composition contain at least one polymer and at least one carbon black having an STSA (statistical thickness surface area) of from about 10 to about 200 m2/g, an I¿2?No of from about 15 to about 250 mg/g, a tinting strength about 130% or less, a DBPA of from about 20 to about 450 cc/100g, a CDBP of from about 20 to about 400 cc/100g, a ratio of I2No to STSA of from about 0.4 to about 2.5, a particle size of from about 14 to about 250 nm, and a %volatiles of less than about 5.0%. Articles for automotive applications and other applications, as well as a method for electrostatically painting an article are also disclosed.

    摘要： Methods to at least partially reduce a niobium oxide are described. In one embodiment, a milling process is described wherein the surfaces of the mill in contact with the staring metal oxide, getter material, and/or oxygen reduced metal oxide are the same as the material being milled. Other milling techniques and products are also described.

    摘要： Extruded tantalum billets and niobium billets are described having a substantially uniform grain size and preferably an average grain size of about 150 microns or less and more preferably an average grain size of about 100 microns or less. The extruded billet can then be forged or processed by other conventional techniques to form end use products such as sputtering targets. A process for making the extruded tantalum billets or niobium billets is also described and involves extruding a starting billet at a sufficient temperature and for a sufficient time to at least partially recrystallize the billet and form the extruded billet of the present invention.
