    摘要： A copper foil for printed circuits including a thermal oxidation-resistant treated layer (e.g., Zn--Ni or Zn--Co alloy plating) formed on the shiny side of the foil and a Cr-base anticorrosive treated layer (e.g., chromate film, mixed film of chromium oxide and zinc and/or zinc oxide, or both) formed further thereon, characterized in that a copper plating layer or an etched surface is provided before forming the thermal oxidation resistant treated layer. The copper plating or etching permits the shiny side to be completely covered with fresh copper or purified to overcome any ununiformity of the chemical activity and/or any lack of smoothness of the entire surface of the shiny side. The evenness of the freshly formed copper surface enhances the homogeneity and completeness of the thermal oxidation-resistant plated layer to be formed subsequently by thermal oxidation resistance treatment, rendering it possible to take the full advantage of the thermal oxidation-resistant treated layer. Thus a surface treatment technique of imparting a thermal oxidation resistance upon heating at 300.degree. C. for 30 minutes to the shiny side of copper foil has now been successfully developed for the first time in the art.

    摘要： A method is provided for producing high purity electrolytic copper useful, for example, to make a copper wire for use in sound or image reproducing systems, such as audio, video and television systems, etc. The copper wire consists of high purity copper in which silver and sulfur contents are both not more than 0.5 ppm and preferably has a crystal grain size not less than 0.02 mm and is unidirectionally solidified or is a single crystal. Such a copper wire is manufactured by continuously casting electrodeposited copper which has been obtained by refining by re-electrolysis of electrolytic copper, using a specially arranged casting apparatus having a mold projecting to an electrolytic bath.

    摘要： A double-metal-coated metal sulfide powder comprises particles of a metal sulfide, a layer of a platinum group metal coating formed thereon, and an outer coating layer of a metal or alloy which contains at least one of iron, copper, nickel, and cobalt. The powder is obtained by forming a platinum group metal layer on metal sulfide particles by thermal decomposition of a plating composition which includes at least one platinum-metal compound containing a radical selected from the class consisting of NO, NO.sub.2, NO.sub.3, and NOCl and then forming a layer of at least one metal selected from the group consisting of iron, copper, nickel, and cobalt by the cementation reaction.

    摘要： A process for granulating metal sulfide powders comprises the steps of adding a solution of thermosetting resin in a volatile organic solvent, as a binder, to a metal sulfide powder as the starting material, forming the mixture thus obtained into granules by a granulator, drying the granulation product, sieving the dried product for classification and recovering the granules within desired limits of particle size, recycling the fines after the sieve classification, with the addition of only the volatile organic solvent, as the material, and heating the granules within the desired limits of particle size for curing. Coarse particles separated out by the sieve classification are pulverized and recycled as the material, with the addition of only the volatile organic solvent.
