MMO Ribbon Anode
MMO Ribbon Anode
The MMO ribbon anode offers high conductivity while maintaining a low consumption rate, ensuring long-term, energy-efficient protection. It features a titanium ribbon substrate coated with an Ir-Ta mixed metal oxide catalyst. This MMO ribbon anode is designed for cathodic protection applications that require high current density in confined spaces. It can be directly buried in fine sand without the need for carbon backfill. Our mixed metal oxide ribbon anodes are ideal for new above-ground tanks with secondary containment linings, as well as existing tanks with double bottom structures.
Titanium conductor rods are commonly used in conjunction with MMO ribbon anodes to serve as inert conductors, ensuring even distribution of the CP current throughout the system. The MMO ribbon anodes are typically spot-welded to the titanium conductor rods at the intersections to create a grid pattern, minimizing attenuation losses. The anodes are then connected to the positive cable using mechanical rod connectors.

MMO Coated Titanium Anodes
Mixed metal oxide coatings on titanium substrates are widely used as anodes in various electrochemical processes, such as chlorination, oxygen production, electrolytic deposition of metals and cathodic protection in the chlor-alkali industry.
The application of materials with high conductivity and long-term stability in electrochemical environments is considered to be one of the main goals of electrochemical cell engineering. Metal oxides such as RuO2 and IrO2, which have high electrical conductivity and electrochemical activity, have received much attention as electrocatalysts in the electrochemical industry. In order to further improve the stability of these oxides, other oxides such as TiO2, Ta2O5 and ZrO2 have been added to these active oxides.
Anodic chloride and oxygen precipitation are the most important reactions in the application of these materials. Oxygen precipitation is the most important reaction in electrochemical processes such as water electrolysis, electrolytic deposition of metals and cathodic protection.
In addition, this reaction is unavoidable in many anodic processes. RuO2-based coatings (e.g. pure RuO2 and RuO2-TiO2) are very stable to the chloride precipitation reaction. However, they are unstable to anodic oxygen precipitation and are subject to severe corrosion in acidic media. IrO2 is more stable for the oxygen precipitation reaction, but its oxygen precipitation electrocatalytic activity is lower. Therefore, due to the favourable properties of the two oxides, a mixture of IrO2 and RuO2 could be a suitable electrocatalyst for the oxygen revolution.
Mixing two or more different oxides can affect the electrocatalytic performance of the oxides by changing the microstructure, surface composition and morphology of the electrocatalyst components. In addition, the surface composition, morphology and microstructure of mixed oxide coatings are not homogeneous and may be affected by preparation factors and active oxide content.
Ruthenium mixed oxide coated titanium anodes are generally used in environments such as hydrochloric acid, electrolytic seawater and electrolytic brine environments.
Fields of application
Electrolytic production of non-ferrous metals, electrolysis of chlorinated salts, electrolysis of salt/seawater, metal foil manufacturing, electrochemical treatment of metal foil surfaces, disinfection, electrolytic extraction and recovery of non-ferrous metals, organic electrolysis, cathodic protection, electrodialysis, production of acidic and alkaline ionised water, treatment of industrial wastewater.

These Platinum plated titanium anode act as inert and non-consumable electrodes, making them very durable. In addition, they remain insoluble in the electrolyte even under the conditions present in the electrolysis process.
Platinum is an ideal anode material due to its excellent electrical conductivity and low consumption rate. However, in view of its status as a precious metal, a cost-effective method of electroplating a thin layer of platinum on a highly corrosion-resistant substrate is usually employed. Titanium, known for its ability to form insulating oxide films under anodic conditions, is a commonly used anode substrate.
Titanium Electrode for Salt Chlorinator
The titanium electrode for salt chlorinator within a salt chlorinator is the component that transforms salt (NaCl) into chlorine. It is composed of a plastic casing and electrodes. Typically, these electrodes are made from titanium, a material renowned for its exceptional corrosion resistance. The anode is generally coated with ruthenium oxide or iridium. The specific makeup of this coating significantly influences both the cell's efficiency in chlorine production and its overall lifespan.
The titanium electrode for salt chlorinator used in the swimming pool salt chlorine generator consists of multiple ruthenium-iridium Coated Titanium electrodes as the anode and uncoated titanium sheets as the cathode. If an inverted electrode descaling operation is to be performed, the cathode also needs to be made from ruthenium-iridium coated titanium. The electrodes, the anode and the cathode are isolated and fixed with polytetrafluoroethylene accessories. This type of electrolytic cell is mostly used for chlorine sterilization in small swimming pools. It can be produced according to the style required by the customer. Giant Anode can provide titanium electrode components, or Electrolyzers with plastic casings are provided for easy use in home swimming pools.

It is made by applying iridium containing and tantalum containing salts on the surface of titanium metal, and after multiple coatings and high-temperature oxidation. The iridium oxide coating and tantalum oxide is obtained. Iridium oxide can effectively reduce the oxygen evolution overpotential and play an electrocatalytic effect. The addition of tantalum oxide effectively increases the service life of the titanium anode. Due to the iridium-tantalum coating Titanium anode has excellent electrocatalytic activity and electrochemical stability. It is widely used in electrolysis industries where the electrolytic medium is highly corrosive, the working environment is harsh, and the current density is extremely high. It is currently recognized as the best oxygen evolution electrode.
