Goodfellow provides cadmium disks with a maximum purity of 99.999% (5N), catering to specialized applications that require its unique properties. Cadmium is known for its low melting point, excellent corrosion resistance, and ability to absorb neutrons. While its use is restricted due to toxicity concerns, it remains crucial in specific industries. Cadmium is used in nuclear reactor control rods, nickel-cadmium batteries, and certain types of solar cells. In research, high-purity cadmium is essential for studying semiconductor physics and developing new photovoltaic materials. Its role in radiation detection and imaging technologies makes it valuable in both medical and scientific fields. The ongoing research into cadmium-based quantum dots highlights its potential in next-generation display and lighting technologies.
