Platinised Niobium

Platinised niobium anodes combine the excellent electrochemical characteristics of platinum with the very good corrosion qualities of niobium.

Platinised Niobium

They are characterised by the following features:

  • 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 

This anode type consists of a niobium base in the form of expanded metal, sheet, rod, wire, or pipe. The standard platinum layer thickness is 2 - 5 µm, in case of higher loads layer thickness of up to 20 µm. Compared to platinised titanium anodes, niobium anodes have a significantly higher breakdown voltage. A longer service lifetime at even higher current densities(up to 100 A/dm2) are achieved in particular when using in baths with low fluoride concentration.
