Ruthenium Iridium Titanium Anode

Ruthenium-iridium-titanium anode is essentially a metal oxide coated anode, which is mainly composed of ruthenium oxide and iridium oxide coated on the surface of titanium substrate. This type of anode is widely used in electrochemical industries such as chlor-alkali, water electrolysis, wastewater treatment, electroplating, and electrowinning.

Why use ruthenium and iridium?

Ruthenium oxide (RuO ₂) has extremely high electrocatalytic activity for chlorine evolution and is the main active ingredient in the chlorine evolution reaction.

Iridium oxide ( IrO ₂ ) provides good corrosion resistance and structural stability, extending the life of the coating.

The two are combined in a ratio (commonly 70:30) to achieve a good balance between electrocatalytic performance and stability.

Analysis of the structure and composition of ruthenium-iridium-titanium anode

The ruthenium-iridium-titanium anode mainly consists of two parts: substrate and coating.

Its base material is titanium, which has excellent mechanical strength and corrosion resistance, and can work stably for a long time in harsh environments such as strong acid and strong alkali. Titanium itself does not participate in the reaction during the electrolysis process, but only acts as a conductive carrier to provide stable support for the anode. It is currently recognized as an ideal anode matrix material in the electrochemical field.

A mixture of ruthenium oxide (RuO₂) and iridium oxide (IrO₂), usually compounded in a certain proportion. This coating has extremely high electrocatalytic activity, can significantly reduce the overpotential in the electrolysis reaction, improve energy efficiency, and is the main reaction layer for key reactions such as chlorine evolution and oxidation. At the same time, the addition of iridium also enhances the structural stability and corrosion resistance of the coating, extending the service life of the electrode.

Precautions for use of ruthenium-iridium coated titanium anode

When avoiding scratches, try to avoid direct contact with the surface of the ruthenium iridium titanium anode with hard objects to prevent mechanical damage to the coating, which will affect its electrochemical properties and service life.

After use, the anode should be rinsed with clean water in time to remove residual electrolyte and impurities, and then stored in a dry, well-ventilated environment to effectively prevent corrosion and contamination and ensure the long-term stability of the anode.

During use, the current density should be strictly controlled to avoid long-term operation under high current conditions and keep it within the range recommended by the manufacturer. This can significantly extend the service life of the anode and ensure its working efficiency.

Ruthenium-iridium-titanium anodes are not suitable for media environments containing fluoride ions. Fluoride ions will damage the coating, causing performance degradation or even failure, so they should be avoided in such environments.

The anodes should be inspected regularly, with a focus on whether there is wear, corrosion or other abnormal phenomena, and maintenance and care should be carried out in a timely manner to prevent potential failures and ensure safe and reliable operation of the equipment.

During operation and maintenance, the instructions and operating guidelines provided by the manufacturer must be strictly followed. Only in this way can the ruthenium iridium titanium anode be guaranteed to perform at its best, extend its service life, and improve its overall economic benefits.
