DSA® anodes

In Electrochemistry the anode is the electrode where the oxidation reaction occurs.  De Nora commercializes its anodes with DSA® brand, very well known in electrochemical industry. The application on a valve metal substrate of a mixed metal oxide (MMO) coating, having catalytic proprieties for a selected anodic reaction, allows a long and stable operation of the DSA® anode in several important industrial applications, including the long-established application in the chlor-alkali industry as well as the most recent utilizations in oxygen evolution.

De Nora produces anodes in a wide range of shapes and sizes utilizing titanium (or different metals) sheet, mesh, wire, rod, strip, plate, wire, tubular or combinations thereof. Their size varies from few cm² to several m².

Anode design is determined by:

  • The electrochemical cell or installation wherein the anodes are used
  • The process conditions, such as electrolyte composition, temperature, current density, design life, etc
  • Mechanical load of the anode
  • Electrical conductivity of the base material
