Formula: Bi
Form: Foil/Film/Sheet
Material: Bismuth
CAS Number: 7440-69-9
Commodity: Metals
Goodfellow offers bismuth foil with a maximum purity of 99.999% (5N). Bismuth's unique properties, including its low melting point and slight radioactivity, make it valuable in various applications. It's used in the production of fusible alloys, pharmaceuticals, and cosmetics. In the electronics industry, bismuth is increasingly important as a lead replacement in solders due to its non-toxic nature. Its thermoelectric properties make it valuable in cooling devices and sensors. In research, high-purity bismuth foil is crucial for studying superconductivity at low temperatures and developing novel materials. The growing importance of bismuth in green technologies and medical applications highlights its significance in both scientific research and industrial innovation.
