Description
Powerful RuO2 Titanium Anode – 99.9% MMO Electrode for Chlorine Generation
🔍 Overview
The RuO2 Titanium Anode is a high-performance electrochemical electrode designed with a 99.9% pure Mixed Metal Oxide (MMO) coating, primarily composed of Ruthenium Oxide (RuO2) and other rare noble metals. Engineered for superior conductivity, corrosion resistance, and extended service life, it is widely used in chlorine generation, water treatment, electroplating, and various electrolytic processes.
Manufactured with precision, this MMO Coated Titanium Electrode ensures consistent performance under aggressive electrochemical environments, offering substantial savings in operational costs by reducing energy consumption and maintenance cycles. Its low overpotential enables higher current efficiencies, while the exceptional coating adhesion to titanium substrate allows long-term use without delamination or passivation.

🌋 Material Composition
The RuO2 Titanium Anode is composed of:
📌 Substrate:
- Commercially Pure Titanium (Grade 1 or Grade 2), known for high corrosion resistance and weldability.
📌 Coating:
- Mixed Metal Oxide (MMO), typically composed of:
- Ruthenium Oxide (RuO2) – for chlorine evolution reaction.
- Iridium Oxide (IrO2) – improves durability under acidic conditions.
- Tantalum Oxide (Ta2O5) or Titanium Oxide (TiO2) – as a stabilizer.
- Coating thickness: 10–30 μm (adjustable upon request)
- Coating Ratio: Ru:Ir can be customized (standard 70:30 or 60:40)
The adhesion between the titanium substrate and the MMO coating is achieved through high-temperature thermal treatment or proprietary sintering techniques that ensure excellent mechanical and chemical bonding.
