摘要:
PROBLEM TO BE SOLVED: To provide a method for fabricating a metallic article without any melting.SOLUTION: A metallic article (20) made of metallic constituent elements is fabricated from a mixture of nonmetallic precursor compounds of the metallic constituent elements. The mixture of nonmetallic precursor compounds is chemically reduced to produce an initial metallic material, without melting the initial metallic material. A consolidation process may be performed by a viable technology. A preferable technology includes hot isostatic press, forging, pressure forming and sintering, and container extrusion of the initial metallic material. The material is consolidated to produce the consolidated metallic article (20). The consolidation is preferably performed by hot isostatic press, forging, pressure forming and sintering, and container extrusion of the initial metallic material.

PROBLEM TO BE SOLVED: To provide a method of forming efficiently and at a low cost a copper-tin alloy foil membrane electrode which is used as an electrode for non-aqueous electrolyte secondary battery. SOLUTION: The copper-tin-containing paste contains tin oxalate and copper acetate of an organic metal compound, tetraethylene glycol, and 1, 2-diamino cyclo-hexane. The copper-tin-containing paste in which a tin precursor containing tin oxalate, tetraethylene glycol, and 1, 2-diamino cyclo-hexane in a ratio of 1 :[2 or more and 4 or less]:[2 or more and 4 or less] by molar ratio and a copper precursor containing copper acetate and tetraethylene glycol in a ratio of 1:[2 or more and 4 or less] by molar ratio are mixed is formed, and the paste is coated on a current collector and calcined, thereby, a uniform thin-film shape copper-tin alloy electrode can be formed.

摘要:
SnO2 powder having a surface area of about 4-15 m /g and an average particle diameter of about 50-200 nm, a method for preparing the SnO2 powder, and a method for making an ITO (indium tin oxide) target. The SnO2 powder is applicable in forming a high-density indium tin oxide target for a high-quality, transparent electrode for a display, such as a liquid crystal display, electroluminescent display, or field emission display.
