HOMOGENIZATION METHOD FOR Cu ALLOY COMPRISING Ru |
| 摘要 |
The present invention provides a homogenization method of a Cu alloy containing Ru, which method comprises a step of adding at least one substance selected from the group consisting of Fe, Ni, FeSi, and Si to a Cu alloy containing at least Ru to homogenize Ru that is segregated within the Cu alloy. The homogenization method improves solubility of Ru in a Cu alloy containing Ru and thus accurate measurement of a precious metal content in the Cu alloy can be performed. |
