Behavior of tellurium during vacuum thermal decomposition of Ag–Cu–Te alloy
Journal of Materials Research and TechnologyAg–Cu–Te alloy is inevitable to be produced in the process from lead-copper anode slime to extract precious metals. It has been prone to the situation where tellurium would deposit on the cathode and affect the quality of silver powders.
