Anode Materials and Applications

1. Titanium and Titanium Alloys

• TA1, TA2, TA9, TA10

• Characteristics: Corrosion resistant, lightweight, easy to form; titanium is used as the substrate in almost all electroplating, electrolysis, and water treatment processes.

• Applications: Electroplating anodes, chlor-alkali electrolysis, wastewater treatment, seawater desalination

2. Platinum (Pt)

• Characteristics: Extremely stable, insoluble

• Applications: High-end electrolysis, analytical electrodes, medical electrodes

3. Iridium (Ir), Ruthenium (Ru), Rhodium (Rh)

• Characteristics: Precious metals with extremely strong catalytic activity.

• Applications: Combined with titanium to form titanium-based coated anodes.

4. Lead/Lead Alloys (Pb)

• Traditional anodes, inexpensive but heavy and toxic.

• Applications: Old-fashioned electrolysis, zinc plating.

5. Stainless Steel

• Only usable under weak corrosion and low current conditions.

• Easily passivated and corroded; unsuitable for long-term anode applications.

6. Aluminum, Copper, Iron

• I. Titanium Anodes: Absolutely unsuitable for use as anodes; they will dissolve, corrode, and contaminate the bath solution upon energization.

II. Most Commonly Used in Industry: Titanium-Based Coated Anodes (DSA Anodes)

These anodes are coated with precious metal oxides on a titanium substrate. Currently, 90% of anodes use this method.

• Titanium-based ruthenium-iridium coating: Resistant to chlorine and chlorine evolution; used in electroplating, wastewater treatment, and chlor-alkali applications.

• Titanium-based iridium-tantalum coating: Resistant to acid and oxygen evolution; used in hard chrome plating, water electrolysis, and acidic environments.

• Titanium-based platinum coating: High-end precision electrolysis.

III. Non-Metallic Anode Materials

• Graphite: Electrolysis, batteries, electroplating.

• Carbon electrodes: Low-end, inexpensive, and easily worn out.

• Ceramic electrodes: Special high-temperature electrolysis.
