Abstract: A covered electrode for welding chloride resistant stainless steel of the type containing about 0.04% carbon, 20% chromium, 24% nickel, 5% molybdenum, and balance iron. The covered electrode provides the capability for producing substantially defect-free stainless steel weld deposits that offer excellent resistance to crevice corrosion, as well as general corrosion in chloride containing environments.

Abstract: A method for reducing passivation of a lithium anode used in a cell having a liquid thionyl chloride cathode is disclosed, characterized in that the anode is coated before the assembly of the cell with a solution of an alkyl 2-cyanoacrylate, a solvent, and lithium perchlorate.

Abstract: The metal content of nickel-cobalt mixed sulfide slurries is recovered by atmospheric oxidation leaching, thereafter removing dissolved copper by metathesis with further mixed sulfide feed, treating the filtrate after liquid-solids separation with ammonia to selectively precipitate cobalt, separating the cobalt precipitate and working up the resulting filtrate to recover nickel.

Abstract: An unsupported particulate catalyst especially useful for methanation reactions is prepared by a method comprising fluid-bed roasting agglomerates of nickel sulfide to form a particulate precursor material which can be reduced to composite particles consisting essentially of a nickel-oxide core with a then coherent adherent layer of nickel thereon, the reduced particles being characterized at the surface by the presence of microcapillary pores interconnecting with each other and the outer surface of the particles.

Abstract: This invention is concerned with a process for dissolving oxidic trivalent cobalt compounds in hydrochloric acid while avoiding the generation of chlorine. It includes the following steps (a) slurrying in water the trivalent cobalt compound to be dissolved and (b) treating the resulting slurry with a reduction agent from the group consisting of methanol, formaldehyde and formic acid and with hydrochloric acid. The contact of the hydrochloric acid with the slurry should occur in the presence of the reducing agent. The rate of acid addition should be controlled to maintain the slurry at a pH above 1.

Abstract: An oxide dispersion-strengthened, nickel-base alloy containing special amounts of chromium, aluminum, tungsten, molybdenum and yttria has a combination of strength properties over a range of temperatures, together with substantial corrosion resistance.

Abstract: Metal values are recovered from mattes containing nickel, cobalt and iron by first suspending the mattes in water, oxygen pressure leaching and then chlorine leaching the residue from the oxygen leach.

Abstract: A composite electrode having a structural electrode member with at least a portion of one surface of the electrode member constructed from a continuous matrix of an anodically passivatable metal infiltrated by a metal capable of forming an electroconductive oxide and having the infiltrating metal at the electrode surface oxidized such that an electric current path is provided through the oxidized surface of the matrix metal. In one embodiment the matrix metal is an electrochemical valve metal, e.g., titanium and the infiltrating metal is lead. Applications for the composite electrode include battery grids and electrochemical processing electrodes.
