Introduction
MMO (mixed metal oxide) titanium anodes combine a titanium substrate with a precious-metal-oxide coating selected for the target electrochemical reaction. The two core MMO families — IrO₂–Ta₂O₅ for oxygen evolution and RuO₂–IrO₂ for chlorine evolution — cover the majority of industrial electrolysis, plating and cathodic protection duty. Actual performance depends on coating chemistry, loading, current density and electrolyte chemistry, and is confirmed per quotation rather than stated as a universal value.
Ehisen applies MMO coatings in controlled multi-layers with measured precious-metal loading, and verifies every batch before dispatch. Each anode is engineered to your substrate dimensions, electrical duty, and operating conditions.
MMO Titanium Anode Formats
Standard formats include plate, mesh, tube, probe and rod. Other shapes and dimensions are produced to drawing.
Engineering Basis
The four inputs below define every MMO anode quotation. Provide them and we will confirm coating thickness, current-density rating and service life together.
| Engineering Item | Required Definition |
|---|---|
| Target reaction | Anodic main reaction (OER / CER / other) and competing reactions |
| Electrolyte | Full composition, acidity, chloride / fluoride, contaminants |
| Electrical duty | Total current, current-density basis, polarity, peaks |
| Design-life basis | Failure criterion and expected operating hours |
Technical Specifications
Standard parameters are listed below; values marked per order are confirmed against your engineering data.
| Parameter | Specification |
|---|---|
| Substrate | Grade 1 / Grade 2 titanium |
| Coating | Mixed metal oxide (IrO₂-based MMO) |
| Coating loading | 8–20 g/m², custom available |
| Shape | Plate / mesh / tube / probe / rod / custom |
| Dimensions | Per drawing (L × W × T) |
| Current density | Confirmed per order |
| Operating temp | Confirmed per order |
| Service life | Confirmed per loading & conditions |
Coating Control & Surface Quality
Coating loading and uniformity are measured, not assumed — the parameters that actually control anode life and current distribution.
Coating Loading & Uniformity
Active coating loading is measured and controlled per batch — the value that sets current-density rating and design life.
Bonding & Thermal Cycling
Adhesion and thermal cycling are checked during production to keep the coating stable under thermal and electrochemical load.
