Abstract:
A process for the manufacturing valve metal anodes is provided. The process includes: providing a valve metal powder; pressing the valve metal powder to form a pellet; first deoxidizing the pellet with a first reducing agent to form a first oxide of reducing agent on the pellet; removing the first oxide of reducing agent from the pellet to form a deoxidized pellet; sintering the deoxidized pellet to form a sintered pellet; second deoxidizing the sintered pellet with a second reducing agent to form a second oxide of reducing agent on the sintered pellet; and removing said second oxide of reducing agent.
