Abstract
Self supporting members of copper containing phosphorus, for example bulk copper anodes or plates, for use as consumable anodes for copper electrodeposition or for melting for alloy production are manufactured by electrodeposition from an electrolyte containing copper ions and a suspension of phosphorus bearing particles having a phosphorus concentration of up to about 5 grams per liter.
Claims14
A method for manufacturing a self-supporting member comprising copper containing phosphorus, comprising:
- providing an electrolyte containing dissolved copper ions and phosphorus bearing particles selected from elemental phosphorus and metal phosphide suspended therein, and having a phosphorus loading of up to about 5 grams per liter;
- providing an electrolytic cell having at least one anode and at least one cathode immersed in said electrolyte;
- and passing electric current between said anode and cathode for a time sufficient to deposit a desired thickness of copper containing phosphorus onto said cathode.
