Goodfellow offers platinum foil with a maximum purity of 99.999% (5N). Platinum's exceptional catalytic properties, high melting point, and resistance to chemical corrosion make it invaluable in various industries. In the chemical sector, it's crucial for catalyzing reactions in fuel cells and in the production of nitric acid. Platinum foil is extensively used in laboratory equipment due to its chemical inertness. In the automotive industry, it's a key component in catalytic converters. For research purposes, high-purity platinum foil is essential in electrochemistry studies, developing new catalysts, and exploring advanced energy conversion technologies. Its biocompatibility makes it valuable in medical devices and implants. The foil's high purity ensures minimal contamination in sensitive measurements, making it ideal for use in studying surface reactions and developing novel materials for clean energy applications.
