AN1221 Platinized Niobium Anode

Description:

Platinum is an excellent anode material due to its high conductivity and low consumption rate. But as one of the precious metals, platinum is often used by electroplating a thin layer over a high corrosion resistance substrate to reduce the cost. Niobium is one of the materials which are often used as an anode substrate.

Applications:

Platinized niobium anodes combine the excellent electrochemical characteristics of platinum with the very good corrosion qualities of niobium. Following is some examples of their applications:
- internal protection of condensers, process equipment etc.
- internal protection of water tanks and pipelines
- protection of reinforced concrete structures

Advantage of platinized niobium anode:

• Production of complex shape anodes possible
• Easy handling, low maintenance
• Low electric resistance
• Excellent corrosion characteristics
• Application also in fluoride containing baths
• Long service life at very high current density
• Dimensional stability
• Replating possible
