General description

Platinum (Pt) based wire is a dense, silvery metal that is highly resistant to corrosion. It is a soft transition metal that is highly ductile and malleable, which makes it useful in electronic industries. It has a high melting point and can be oxidized at 500°C.

Application

Pt wires can be used for a wide range of applications such as:
  • reference electrodes for electrochemical processes
  • for the formation of microchannels for microfluidic devices
  • coiling of an optical fiber
  • development of cathode for electrolyte based fuel cells
