Common Questions

Select a question to read the answer.

What is an MMO titanium anode?

It consists of a titanium substrate with an active mixed metal oxide coating. Shape, coated area, connection and coating direction depend on the electrolyte, target anodic reaction and equipment.

How do Ru-based and Ir-based coatings differ?

Ruthenium-iridium oxide coatings are commonly considered for chlorine evolution in chloride media; iridium-tantalum oxides are commonly considered for oxygen evolution. These are starting points. Electrolyte chemistry, current density, temperature and duty determine which formulation needs testing in your cell.

What affects the service life of an MMO anode?

Service life varies with current density, electrolyte composition and impurities, temperature, flow, cleaning and duty cycle. Use operating records and a test under intended conditions to set a project-specific service target.

Is recoating possible for a used MMO anode?

Recoating may be possible if the titanium substrate and connections remain suitable. Share photos, dimensions, operating history and contamination details for a feasibility assessment before assuming the anode can be reused.

Can MMO anodes operate with polarity reversal?

Include reversal frequency, current, timing and duty in the specification. These conditions affect the reaction and electrode arrangement, so suitability must be evaluated for the intended cycle and cell.

How are price and quantity determined?

Quote scope depends on the drawing, titanium form, coating direction, dimensions, connections, inspection requirements, packing, destination and requested quantity. Include sample, pilot or production quantities where available.

What details help prepare a quotation?

Provide the application, target reaction, electrolyte and pH, current or current density, temperature, duty, dimensions, active area, titanium form, connection and quantity. A drawing or current-anode photos help define fit.

Can I discuss confidentiality before sharing a drawing?

Yes. Request a confidentiality discussion before sending detailed drawings or process data. Agree on file handling and any required arrangements before sharing sensitive material.
