<p>Electrolytes containing water, phosphoric acid, at least one organic solvent, and at least one alkanolamine can be used for anodizing valve metals prepared from metal powder having a surface area of least.35 m2/g or 35,000 CV/g. The anodizing electrolytes have relatively high conductivity and are capable of being used at high anodizing currents. The anodic film produced by these electrolytes on valve metals is of substantially uniform thickness and has improved electrical parameters.</p> |
