Mixed Metal Oxide

 

Platinum & MMO Coated Anodes

Mixed metal oxide (MMO) electrodes are devices with useful properties for chemical electrolysis. In Tianode the MMO (Mixed Metal Oxide) Coating has been designed for use in all cathodic protection applications.

MMO Coating

 

MMO Coated Anodes are manufactured by coating a mixture of precious metal oxides on a specially treated precious metal. The coated substrate undergoes multiple thermal treatments at elevated temperatures to gain good bonding properties between the substrate & coating. This bonding property increases the lifetime of anodes. It consists of IrO₂ / Ta₂O₅, suitable for use in soils, carbonaceous backfill, fresh and brackish water, seawater and concrete. Mixed metal oxide coating is generally accepted by the cathodic protection industry to be satisfactory for both chlorine and oxygen evolving electrolytes.  TiTaN’s MMO coated anodes are in high demand in the global market for its excellent electrolytic properties and low wear rate of the coating.

Tubular Anodes

Mixed Metal Oxide (MMO) tubular anodes are titanium tubes with a mixed metal oxide coating. The mixed metal oxide is a crystalline, electrically-conductive coating that activates the titanium and enables it to function as an anode.

MMO Wire Anodes

 

MMO wire anodes are copper cored titanium wire with mixed metal oxide coating.

MMO Disk Anodes

The MMO Disk Anode was developed for cathodic protection of dam and navigation lock gates.

The Advantages of MMO Coating Anode are Long life, Small polarization, low consumption rate and lightweight and non-brittle. Applications include electrolytic cells for producing free chlorine from saltwater in swimming pools, and anodes for cathodic protection of buried or submerged structures.

We provide an excellent chemical corrosion resistance such as acid condition. Our standard outputs are,

 

Electrolyte	Maximum Current Density	Anode Life
Carbonaceous Backfill	50 A/m2	20 years
Calcined Petroleum Coke	100 A/m2	20 years
Fresh Water	100 A/m2	20 years
Brackish Water	300 A/m2	20 years
Sea Water	600 A/m2	20 years

Platinum & MMO Coated Anodes

DSA Anode its stands for Dimensionally Stable Anode (DSA)

Dimensionally stable anodes are a family of advanced titanium base anodes with proprietary Mixed Metal Oxides (MMO) coating.

 

The anode in all technologies is titanium metal coated with an electrocatalytic layer of mixed oxides. All modern cells use these so-called “dimensionally stable anodes" (DSA). Earlier cells used carbon based anodes.

Platinised Titanium Anodes

A modern anode used in brine electrolysis. It is essentially a sheet of titanium metal coated with a mixture of active metal oxides; the coating is stable and has a very long life time under cell operating conditions. Contrast it with the traditionally used carbon electrode that was slowly consumed during cell operation; it had to be replaced periodically and required the rebuilding of the cell. 

    

In general, electrodes are available in the form of  rod, wire, plate, mesh,  ribbon  and customs built. Electro catalytically selective Electrodes from Ti are superior to conventional Nickel, Lead, Lead alloy, Steel, Graphite & Magnetite Electrodes.

Titanium Anode Baskets

Tianode normally, Electrodes (Anodes & Cathodes) consist of a basic component,  the family of titanium has the character for mechanical stability and uniform current distribution insoluble electrodes are manufactured with titanium as basic components,  Occasionally electrodes are also made from Nb, Ta and or Zr.
