| titleOfInvention | Method for producing high-purity electrolytic copper |
| abstract | The method for producing high-purity electrolytic copper of the present invention is characterized in that a first additive (A) containing an aromatic ring containing a hydrophobic group and a polyoxyalkylene group containing a hydrophilic group, and a second additive (A) composed of polyvinyl alcohols are combined. The additive (B) and the third additive (C) composed of tetrazoles are added to the copper electrolyte, and the respective concentrations of the first additive (A), the second additive (B) and the third additive (C) are controlled and the Current density and bath temperature to conduct copper electrolysis, thereby producing electrolytic copper with an Ag concentration of less than 0.2 mass ppm, a S concentration of less than 0.07 mass ppm, and a total impurity concentration of less than 0.2 mass ppm, and the average orientation difference within the crystal grains (referred to as The crystal grains with a GOS value) exceeding 2.5° are 10% or less in terms of area ratio. |
