Bismuth Disk
Goodfellow's bismuth disks, available with a maximum purity of 99.999% (5N), offer unique properties that make them valuable in various applications. Bismuth is known for its low melting point, slight radioactivity, and tendency to expand upon solidification. These characteristics make it useful in the production of alloys, pharmaceuticals, and cosmetics. In the electronics industry, bismuth is increasingly used 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 is crucial for studying superconductivity at low temperatures and in the development of novel materials. The growing importance of bismuth in green technologies and medical applications underscores its significance in both scientific research and industrial innovation.
