Titanium anode tube, also known as MMO tubular anode or precious metal oxide titanium anode tube, is a layer of metal oxide with electrocatalytic activity over a tubular titanium substrate. MMO tubular anode is suitable for many environments, such as soil, fresh water, saline water and seawater, It has high cost performance.
Cathodic protection is divided into sacrificial anode protection method and impressed current protection method. With the rise of MMO titanium anodes, the development of technology and the requirements of environmental protection, the impressed current protection method has been rapidly developed in developed countries.
MMO-coated titanium anodes are a type of DSA anode, which are coated with mixed metal oxides such as ruthenium-iridium and iridium-tantalum on a titanium substrate. Before that, the common anode material was graphite - graphite is the raw material for pencil cores, which you must recognize.
