ABSTRACT:
A method of anodizing porous tantalum material suitable for making a porous tantalum capacitor pellet or slug having decreased current leakage is described. After a pellet is anodized at a maximum predetermined desired voltage, it is removed from the anodizing bath and heated to a temperature of between 150.degree. C. and 300.degree. C. The pellet is maintained at such temperature for at least three minutes and then returned to the anodizing bath, at least once, and subjected to more electrical current.
