NICKEL COPPER COATED POWDER, AND PRODUCTION METHOD OF NICKEL COPPER COATED POWDER
PROBLEM TO BE SOLVED: To provide a method for producing nickel copper coated powder by a simple step and at an efficient cost, the method in which the surface of inorganic powder is coated with copper and the surface of the copper is coated with nickel or a nickel alloy.SOLUTION: A production method of nickel copper coated powder includes a copper coating step for mixing copper oxide powder and a copper salt having a melting point of 700°C or lower with inorganic powder, reducing the obtained mixture by heating at a temperature of 350-800°C under a reducing atmosphere and thus adhering copper to the inorganic powder to obtain copper coated powder and a nickel coating step for forming a film of nickel or a nickel alloy on the surface of the copper coated powder by electroless plating to obtain nickel copper coated powder.SELECTED DRAWING: Figure 1
【課題】無機質粉体の表面に銅を被覆し、さらにその銅の表面にニッケル又はニッケル合金を被覆したニッケル銅被覆粉体を、単純な工程で、コストの面でもより効率的に製造することができる方法を提供する。【解決手段】本発明に係るニッケル銅被覆粉体の製造方法は、無機質粉体に、酸化銅粉と、さらに融点が７００℃以下である銅塩とを混合し、この混合物を還元雰囲気中で３５０〜８００℃の温度で加熱還元することにより、その無機質粉体に銅を付着させて銅被覆粉体を得る銅被覆工程と、銅被覆粉体の表面に、無電解めっき法によりニッケル又はニッケル合金被膜を形成させてニッケル銅被覆粉体を得るニッケル被覆工程と、を有する。【選択図】図１
