General description
This platinum foil is a thin sheet of platinum with a thickness of 0.025 mm and high chemical purity. Platinum is a dense, silver-white metal that is highly resistant to corrosion and has a high melting point. Platinum is a precious metal that is valued for its rarity and chemical stability, and is often used in jewelry, coins, and other decorative objects. In material science, it is often used as electrodes in fuel cells, batteries, and other electrochemical devices, as a substrate for electroplating, and as an inert crucible or dish among other applications.
Application
Platinum foil can be used for a variety of applications such as:
- growth of high crystalline boron nitride (BN) material for UV optoelectronic devices.[1]
- fabrication of electrochemically stable microelectrode arrays[2]
- a counter electrode for the fabrication of supercapacitors
- an enzyme electrode probe for potential usage in biosensors
