Description
Grade 7 Titanium Anode – MMO Coated
🔎 Introduction
The GR7 Titanium Anode combines palladium-bearing titanium with a coating selected for electrolysis, seawater treatment, or impressed current cathodic protection. Specify the drawing, substrate form, active area and electrolyte before selecting the MMO coating and the required current duty, inspection criteria and design-life basis. Substrate corrosion resistance and finished-electrode performance are evaluated for the intended service.
For a quotation on GR7 Titanium Anodes, send electrolyte composition, pH, temperature, current density and duty, coating formulation/loading, connection details, quantity and required order documents.
🧪 What is a GR7 Titanium Anode?
The GR7 Titanium Anode uses Grade 7 titanium (Ti–0.12Pd catalogue notation), a palladium-bearing titanium grade. The published material reference gives palladium at 0.12–0.25%; confirm the ordered material specification and lot analysis. Palladium can improve resistance to particular corrosive environments, while coating and operating conditions govern anode performance.
A coating of Mixed Metal Oxides (MMO) may use IrO₂, RuO₂ and Ta₂O₅ in a formulation selected for the target reaction. This creates an MMO-coated titanium electrode for the specified process. Confirm formulation, substrate and life-assessment requirements for the actual electrolyte.
✅ Key properties of GR7 Titanium Anode:
-
Palladium-bearing substrate selection for the specified corrosive medium
-
Service-life assessment for the selected coating loading and current duty
-
Current-density and active-area requirements defined for the selected process
-
Compatibility with multiple anode geometries (plate, mesh, tube, rod)
⚡ MMO Coating Technology
The performance of a GR7 Titanium Anode depends on the selected MMO coating. Confirm the formulation, loading, surface preparation and processing route in the order, together with the electrolyte and target anodic reaction.
Composition of MMO Coatings
-
Iridium Oxide (IrO₂): A catalytic component whose suitability is assessed in the complete coating for the intended reaction and electrolyte.
-
Ruthenium Oxide (RuO₂): A catalytic component often considered for chlorine-evolving service; select the complete formulation for the actual electrolyte.
-
Tantalum Oxide (Ta₂O₅): A component of some mixed-oxide formulations; confirm the composition and coating stability requirements for the order.
✅ Advantages of MMO Coating:
-
Electrocatalytic formulation selected for the target reaction
-
Energy assessment under defined cell geometry and operating conditions
-
Catalogue life reference (8–12 years): confirm loading, duty and life-assessment basis
-
Adhesion inspection method and acceptance criteria specified in the order
-
Coating compatibility assessed for the specified electrolyte

| Corrosion Resistance | High | High | Superior in chloride media |
| Mechanical Properties | Good ductility | Higher strength than GR1 | Similar to GR2 |
| Crevice/Pitting Corrosion | Moderate | Moderate | Excellent resistance |
| Typical Applications | General electrolysis | Electroplating, CP | Seawater, Chlor-alkali, Harsh Cl environments |
👉 Selection note: Compare GR7 Titanium Anodes with GR1/GR2 configurations using the actual chloride concentration, temperature and current duty. The comparison above is a substrate-selection reference; the ordered grade, coating and process conditions determine suitability.
🌟 Key Advantages of GR7 Titanium Anode
🛡 1. Substrate Corrosion Selection
Palladium-bearing titanium offers corrosion-selection options for particular solutions. For offshore structures, desalination plants, or seawater electrolysis units, confirm chemistry, concentration, pH, temperature and the selected coating before ordering.
🔋 2. Service-Life Basis
The stated 8–12 years is a catalogue reference requiring a defined coating loading, electrolyte, current density, duty and life-assessment method. Agree the project design life and supporting evidence in the quotation.
⚙️ 3. Current and Energy Assessment
The catalogue current-density reference of 100–500 A/m² requires confirmation for the selected MMO formulation, active area, electrolyte and current duty. Evaluate energy use with measured comparison data under the same cell geometry and operating conditions.
🌍 4. Process and Effluent Requirements
For a GR7 coated titanium anode, define the process and effluent requirements. Chlorine or oxygen generation and coating wear depend on the electrolyte and operating conditions; agree the applicable environmental and process acceptance criteria.
📏 5. Dimensional Stability
An MMO-coated titanium anode is designed to maintain electrode geometry during the intended duty. Confirm coating wear, substrate condition, mounting and the inspection criteria needed to maintain electrode spacing.
