    摘要: An MgB2 superconducting wire excellent in critical current density property is supplied by using a crystalline boron powder which is low in costs and easy to obtain. For the wire, a precursor of the MgB2 superconducting wire is used, the precursor having a linear structure including a core region containing a magnesium powder and a boron powder, and a sheath region formed of a metal covering an outer circumferential portion of the core region. The boron powder is crystalline, and has a volume-mean particle size of 2 μm or less.

    摘要: Disclosed herein are copper powder, a copper paste and a method for preparing a copper powder. The copper powder is provided with a cuprous oxide film having a loose structure on a surface of the copper powder, thereby preventing the copper particles from being naturally oxidized, making it possible to being subjected to a low temperature firing process and having improved conductivity.
