Electroplated platinum anodes-epma. Platinum is a precious metal having very good physical and chemical properties such as
  • High corrosion resistance
  • Thermal conductivity
  • Catalytic nature
As it is very expensive, platinum cannot be used in its solid form as an anode. So that Platinised Metal Anodes ( Pt Anode ) are produced by electroplating platinum ( Pt ) on a specially treated precious metal (Titanium / Niobium / Tantalum / Zirconium ) substrate by means of electrodeposition process.

Thus electroplated metal anodes are economical as well as it retains the superior physical and chemical properties of platinum.

According to the substrate material used, the platinized anodes are called as
  • Electroplated titanium anode ( EPMA -Ti )
  • Electroplated niobium anode ( EPMA -Nb )
  • Electroplated zirconium anodes ( EPMA -Zr )
  • Electroplated tantalum anodes ( EPMA -Ta )
TiTaN's electroplated metal anodes are most suitable to various critital special applications.

  • Platinized anodes are having better conduction properties platinized titanium mesh anode for Mixed Metal Oxide Coated Anodes ( MMO Anode )
  • Platinised Anodes ( Pt Anode ) are produced by coating platinum ( Pt ) on a specially treated precious metal (Titanium / Niobium / Tantalum / Zirconium ) substrate by means of electrodeposition process. They are economical as well as it retains the superior physical and chemical properties of platinum.
According to the substrate material used, the platinized anodes are classified as
  • Platinized titanium anode
  • Platinized niobium anode
  • Platinised zirconium anodes
  • Platinised tantalum anodes

Platinized niobium wire anodes are designed for effective operating in fresh, brackish and saltwater; used in all types of aqueous storage and process equipment. These anode aren't adversely affected by high chloride concentrations. Also platinized tubular / rod anodes are used for cathodic protection in seawater environment Because of its low consumption rate, the anode may be employed in a cathodic protection system to achieve a long life.

Platinum, Palladium, Rhodium, Ruthenium, Iridium and Osmium are found as a part of Platinum Group Metals (PGM’s). Pure platinum is a tin white metal, it is malleable ductile, and harder than silver. It does not tarnish in air and dissolve in acid.

Ti Anode Fabricators Pvt Ltd, India is providing solution by depositing platinum on titanium, niobium, molybdenum, stainless steel, brass, aluminum & copper by electro deposition process. In electrochemical application, Niobium is selected as substrate, when the resistivity of titanium is too high or its breakdown potential is too low. Platinized niobium is preferred for high current application.
