1. Ruthenium–Titanium Anode Plate
Advantages:
Ruthenium–Titanium anodes deliver high current efficiency for both chlorine and oxygen evolution reactions. They exhibit excellent corrosion resistance, long operational life, and can be fabricated in customized dimensions. The titanium substrate can be reused multiple times, and the anode introduces no contamination to the electrolyte or product.
Applications:
Widely used in the chlor-alkali industry, sodium hypochlorite generation, industrial wastewater treatment, and freshwater disinfection.
2. Ruthenium–Iridium–Titanium Anode Plate
Advantages:
The dimensional stability of Ru–Ir–Ti anodes ensures a constant electrode gap during operation, maintaining stable cell voltage. Their low operating voltage and high energy efficiency can reduce overall power consumption by up to 20%.
In diaphragm-based chlorine production, titanium anodes show strong resistance to both chlorine and alkali corrosion, effectively overcoming the dissolution issues of graphite and lead anodes. This eliminates contamination of the electrolyte and cathode products, improving product purity and extending service life.
In practical terms, during diaphragm chlor-alkali production, the current density of a graphite anode is about 8 A/m², while a titanium anode can reach approximately 17 A/m², effectively doubling output without changing cell capacity. The titanium substrate also resists deformation and corrosion, preventing short circuits and maintaining consistent current efficiency.
Applications:
Chlor-alkali production, chlorine dioxide, chlorate and hypochlorite synthesis, perchlorate production, hospital wastewater treatment, persulfate manufacturing, food-grade disinfection, and ionized water generation.
3. Tantalum–Iridium–Titanium Anode Plate
Advantages:
In sulfuric acid electrolytes where oxygen evolution occurs at the anode, Ta–Ir–Ti anodes provide a low oxygen overpotential and strong electrolyte corrosion resistance. The iridium oxide coating offers outstanding durability - the initial anode potential of 1.51 V rises only to 1.64 V after 6000 hours, with virtually no coating loss (0 mg/m²).
By contrast, conventional lead alloy electrodes (containing 6–15% Sb or ~1% Ag) tend to dissolve during operation, leading to anode consumption, solution contamination, and reduced metal purity due to lead deposition at the cathode. Ruthenium-based coatings also degrade rapidly under these acidic conditions. Tests show an initial potential of 1.48 V, increasing to 2.0 V within 1000 hours, indicating severe passivation.
Applications:
Used in non-ferrous metal electrolysis, silver catalyst production, textile and dyeing wastewater treatment, electrolytic copper foil manufacturing, steel galvanizing, chromium plating, mercury recovery, rhodium/palladium/gold plating, water electrolysis, molten salt electrolysis, battery production, cathodic protection, ionized water systems, and PCB manufacturing.
4. Iridium–Tin–Titanium Anode Plate
Advantages:
This anode type offers high current efficiency under chlorine or oxygen evolution conditions, excellent chemical resistance, and long service life. The electrode substrate can be refurbished and reused, while maintaining a contamination-free electrolyte.
Applications:
Applied in chlor-alkali plants, aluminum and copper foil production, industrial wastewater treatment, ionized and electrolyzed water systems, electrochemical oxidation of organic pollutants, organic electro-synthesis, gas purification, seawater desalination, and oxidant regeneration.
