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
