摘要:
A lead oxide-coated electrode for use in electrolysis is disclosed, which comprises a primary layer comprising platinum and/or palladium oxide, an intermediate layer comprising α-PbO₂, and a coating layer comprising β-PbO₂ successively coated on a substrate comprising a corrosion resistant metal. The electrode has a strong and durable lead oxide coating firmly bonde d to the substrate, does not suffer from passivation, resistance increase, etc. and can be used stably for a long time at high current density. A process for producing the electrode is also disclosed.
