Ruthenium-based MMO Coated Titanium Anode

Specifications

• Substrate: TA1/TA2
• Coating:Pure ruthenium, ruthenium-iridium, ternary ruthenium-iridium, multicomponent ruthenium-iridium mixed oxide formulations
• Operating Environment: Generally used in hydrochloric acid, electrolyzed seawater, and electrolyzed brine environments
• Dimensions: Customized according to requirements
• Shape: Plate, mesh, tubular
• Current Density: ≤ A/m2

Features

• The coating can be customized with different formulations for various operating environments. The improved nanoscale refined grains enhance the bonding between the coating and the substrate, leading to better electrocatalytic performance.
• The chlorine evolution overpotential is reduced, which extends the electrode's service life and provides good corrosion resistance.
• The size and shape of the anode can be customized based on actual working conditions to meet specific needs.
• Anode recoating services are available based on the wear of the anode coating. The substrate can be reused multiple times without excessive wear, saving costs for the user.

Application Fields

• Non-ferrous metal electrolytic production
• Chlor-alkali electrolysis
• Seawater electrolysis
• Manufacture of metal foils
• Electrochemical surface treatment of metal foils
• Electrolytic extraction and recovery of non-ferrous metals
• Organic electrolysis
• Cathodic protection
• Electrodialysis
• Production of acidic and alkaline ionized water
• Industrial wastewater treatment and other fields.

• The size and shape of the anode can be processed and customized according to the actual working conditions, meeting different demands.
• Anode recoating services are available based on the wear of the anode coating. The substrate can be reused without excessive wear, saving costs for the user.

Application Fields

• Non-ferrous metal electrolytic production
• Recovery of electrolytic copper from etching solutions
• Electrochemical surface treatment of metal foils
• Auxiliary anodes for electroplating
• Organic electrosynthesis
• Cathodic protection
• Electrodialysis
• Production of acidic and alkaline ionized water
• Industrial wastewater treatment and other fields.

Platinum-based MMO Coated Titanium Anode

Specifications

• Substrate: TA1/TA2, Nb1/Nb2
• Coating: Pure platinum, platinum-iridium
• Processing Techniques: Electroplating, brush plating
• Coating Thickness: 0.3 - 10 μm
• Shape: Commonly in plate, mesh, tubular, wire, or custom shapes; dimensions can be customized according to practical needs

Features

• Compared to pure platinum anodes, titanium-based platinum-coated anodes have relatively lower costs, making them a common choice where economics are considered.
• The platinum coating endows the anode with excellent electrocatalytic activity, facilitating the efficient progression of related electrochemical reactions.
• Titanium-based platinum-coated anodes, owing to their material properties, are suitable for a variety of chemical reactions and process scenarios.

Application Fields

Electrolytic chlorine plants, breweries, paper mills, and the manufacturing of chemicals such as reagents, perchlorates, and chlorates.
