What Is an MMO Titanium Anode and How to Choose the Right One for Your Industry?
MMO Titanium Anode (Mixed Metal Oxide Titanium Anode) is a high-performance dimensionally stable insoluble electrode for industrial electrochemical applications. It adopts industrial pure titanium as the substrate, with a high-adhesion precious metal oxide coating (ruthenium, iridium, tantalum and composite oxides) plated on the surface.
Compared with traditional graphite, lead and high-silicon cast iron electrodes, MMO titanium anodes feature superior corrosion resistance, stable electrochemical performance, lower energy consumption and far longer service life. They effectively avoid electrode dissolution, sludge generation and frequent replacement problems of conventional consumable electrodes.
With excellent conductivity and electrocatalytic activity, our MMO coated titanium anodes maintain stable operation in extreme environments including strong acid, strong alkali, high chloride and high-salinity seawater. Widely applied in water treatment, electroplating, chlor-alkali production, electrolytic protection, seawater electrolysis, hydrogen production and metal recovery, they have become the mainstream preferred electrode for global energy-saving and environmentally friendly electrochemical industries.
