AI Technical Summary
In existing methods for preparing electronic-grade copper oxide, incomplete or excessive reactions lead to cumbersome processes, low production efficiency, and the need to handle excessive reaction products and residual reactants, which also affects production efficiency.
Barium carbonate is used as a precipitant to react with copper sulfate to form basic copper carbonate. High-purity copper oxide powder is obtained by heating and decomposing a copper ammonia complex solution, avoiding the use of carbon dioxide and oxidizing gases and simplifying the process.
This method yields high-purity copper oxide powder with low metal impurity ion content, which dissolves quickly, reduces production costs, improves production efficiency, simplifies the process, and reduces energy consumption.
