  • Patent number: 8197574
    Abstract: A method of making dispersion-strengthened alloy particles involves melting an alloy having a corrosion and/or oxidation resistance-imparting alloying element, a dispersoid-forming element, and a matrix metal wherein the dispersoid-forming element exhibits a greater tendency to react with a reactive species acquired from an atomizing gas than does the alloying element. The melted alloy is atomized with the atomizing gas including the reactive species to form atomized particles so that the reactive species is (a) dissolved in solid solution to a depth below the surface of atomized particles and/or (b) reacted with the dispersoid-forming element to form dispersoids in the atomized particles to a depth below the surface of said atomized particles. The atomized alloy particles are solidified as solidified alloy particles or as a solidified deposit of alloy particles.

  • Patent number: 8173093
    Abstract: Provided is an iron silicide sputtering target in which the oxygen as the gas component in the target is 1000 ppm or less, and a manufacturing method of such iron silicide sputtering target including the steps of melting/casting high purity iron and silicon under high vacuum to prepare an alloy ingot, subjecting the ingot to gas atomization with inert gas to prepare fine powder, and thereafter sintering the fine powder. With this iron silicide sputtering target, the amount of impurities will be reduced, the thickness of the ?FeSi2 film during deposition can be made thick, the generation of particles will be reduced, a uniform and homogenous film composition can be yielded, and the sputtering characteristics will be favorable. The foregoing manufacturing method is able to stably produce this target.

  • Patent number: 8158092
    Abstract: Provided is iron silicide powder in which the content of oxygen as the gas component is 1500 ppm or less, and a method of manufacturing such iron silicide powder including the steps of reducing iron oxide with hydrogen to prepare iron powder, heating the iron powder and Si powder in a non-oxidizing atmosphere to prepare synthetic powder containing FeSi as its primary component, and adding and mixing Si powder once again thereto and heating this in a non-oxidizing atmosphere to prepare iron silicide powder containing FeSi2 as its primary component. The content of oxygen as the gas component contained in the iron silicide powder will decrease, and the iron silicide powder can be easily pulverized as a result thereof. Thus, the mixture of impurities when the pulverization is unsatisfactory will be reduced, the specific surface area of the iron silicide powder will increase, and the density can be enhanced upon sintering the iron silicide powder.

  • Patent number: 8057750
    Abstract: A process of producing magnetite with a high purity of greater than 90% magnetite, more typically greater than 98% magnetite, by reducing powdered hematite into magnetite under maximum temperatures of about 700 to 1300° C. against a counter-current of or concurrent with methane or natural gas in a heating device. The amount of methane used to reduce the hematite may be about 0.18 and 1.8 standard cubic feet of methane per pound of hematite. A product of high purity methane produced from the process is also provided, where the magnetite is below 1 ?M in diameter and has a magnetic saturation greater than 90.0 emu/g. Corresponding apparatus using an improved feeder system for powdered hematite is provided.

  • Patent number: 8034152
    Abstract: A novel solution route has been developed that after heat-treatment to 500-600° C. under inert atmosphere, yields highly porous composites of nano-sized metal (Ni) particle inclusions in ceramics (Al2O3). Metal loadings could be made from <1% to >95% Ni. The metal inclusion sizes in the Ni—Al2O3 system with the 10 atom % Ni sample were 4-7 nm, while for the 75 atom % Ni sample they were 5-8 nm. It was shown that the 10 atom % Ni sample could be used as a catalyst for the conversion of CO2 and CH4 in the temperature range 550-700° C., while higher temperatures led to growth of the Ni particles and carbon poisoning over time. The solution routes could also be deposited as thin dense films containing <10 nm Ni particles. Such films with high Ni-particle loadings deposited on aluminium substrates have shown very good solar heat absorber proficiency and provide good substrates for carbon tube growth.
