Abstract

Official abstract text for this publication.

A method of producing copper oxide powder includes a high-purity copper acidic solution preparation step (S 01 ) of preparing an acidic solution containing 99.99% by mass or more of copper regarding metal components as 100% by mass, an organic acid salt addition step (S 02 ) of adding an organic acid salt to this high-purity copper acidic solution, an organic acid copper production step (S 03 ) of generating an organic acid copper by reacting the added organic acid salt with copper ions, an organic acid copper recovery step (S 04 ) of recovering the obtained organic acid copper, and a heating step (S 05 ) of forming copper oxide powder by heating the recovered organic acid copper, in which the organic acid forming the organic acid salt has 10 or less carbon atoms, and copper oxide powder.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method of producing copper oxide powder comprising: a high-purity copper acidic solution preparation step of preparing an acidic solution containing 99.99% by mass or more of copper regarding metal components as 100% by mass; an organic acid salt addition step of adding an organic acid salt to the high-purity copper acidic solution; an organic acid copper production step of producing an organic acid copper by reacting the added organic acid salt with copper ions; an organic acid copper recovery step of recovering the obtained organic acid copper; and a heating step of forming a copper oxide powder by heating the recovered organic acid copper, wherein an organic acid forming the organic acid salt has 10 or less carbon atoms. 2 . A copper oxide powder wherein a content of sodium which is an impurity is 5 mass ppm or less regarding metal components as 100% by mass. 3 . A Copper oxide powder according to claim 2 , wherein a total content of metal impurities is 30 mass ppm or less regarding the metal components as 100% by mass.
