Document Type and Number:
WIPO Patent Application WO/2024/048851
Kind Code:
A1
Abstract:
The present invention is technically characterized in that copper and zinc are alloyed by comprising: a first step of mixing a copper or copper oxide powder and a zinc powder to prepare a mixture powder; a second step of thermally treating the mixture powder in a reducing atmosphere to prepare a copper-zinc alloy powder; a third step of thermally treating the copper-zinc alloy powder in an oxidizing atmosphere to prepare a copper oxide-zinc oxide alloy powder; a fourth step of pulverizing the copper oxide-zinc oxide alloy powder to prepare a pulverized copper oxide-zinc oxide alloy powder; and a fifth step of thermally treating the pulverized copper oxide-zinc oxide alloy powder in a reducing atmosphere to re-reduce the pulverized copper oxide-zinc oxide alloy powder to a copper-zinc alloy powder.
