Description of Expanded Mesh Mixed Metal Oxide Electrode

Expanded Mesh Mixed Metal Oxide Anodes (MMO Anodes), also called dimensionally stable anodes, are a type of impressed current protection anode that consists of rare earth oxide coated onto titanium substrate. MMO coating has a low consumption rate, make the metal dimensions remain constant during the working life of the anode, which provides a consistently low resistance anode. It is usually used in environments such as seawater, brackish water, fresh water, carbon backfill, and concrete.

What is Mixed Metal Oxide?

Mixed metal oxide (MMO) refers to a coating used in cathodic protection applications. It consists of an electrocatalytic component that facilitates current flow and bulk oxides that protect the substrate from corrosion.

Ruthenium oxide and iridium oxide are common electrocatalysts, with iridium oxide being preferred for its versatility in different environments. The bulk oxides, usually a mix of titanium dioxide and tantalum oxide, form an oxide film over the substrate to prevent corrosion. Each supplier has a unique recipe for their MMO coating, tailored to specific application needs.
