Mixed Metal Oxide

The mixed metal oxide (MMO) coating is a crystalline electrically conductive coating that activates and enables a titanium substrate to function as an anode. the coating consists of iridium and tantulum oxides and is suitable for use in soils, carbonaceous backfill, fresh and brackish water, seawater (with added oxides of Ruthenium) and concrete.
