Ruthenium Iridium Titanium Anodes

Basic information

Because of a very flexible production facility, we are able to manufacture anodes of all types: sheet, plate, mesh, wire, rod, tubular or combinations and/or assemblies of these materials. Their size and number vary from several cm2 to 2 m2 and from 1 to 10,000 pieces. The process in which the anodes are used determines size, shape and coating specification of an anode.

Important parameters determining the anode design are:

◆ 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

◆ Capacity of electrical conductivity of the base material.

All anodes are produced according to customer specifications. When these specifications are not yet completely determined, our engineers are pleased to use their knowledge and experience to finalise the design together with the customer.

Main application areas	Anodes and coatings	Details
Cathodic Protection	KERAMOX® Titanium anode Platinised Titanium Anodes based on Niobium or Tantalum	All round applicable At high current densities, for example in sea water High voltages or strongly corrosive electrolytes
Seawater electrolysis	KERAMOX® Titanium anode Titanium with a Ruthenium Mixed Metal Oxide coating Titanium with a Platinum-Iridium Oxide coating	Depending on amongst others temperature and salinity
Electroplating	Titanium with an Iridium Mixed Metal Oxide coating Platinised Titanium	In highly acidic environments such as: Electro galvanising (zinc plating) Anodising of Aluminium Chromium, Nickel,Tin, etc. plating Precious metal plating Reverse pulse Copper plating Hard Chromium plating Precious metal plating
Water treatment	Platinised Titanium Titanium with an Iridium Mixed Metal Oxide coating Boron-Doped-Diamond anodes	Electro dialysis with polarity reversal Recovery of metals Oxidation and break-down of organic contaminations Higher overpotentials,amongst others for disinfection
