Formula: Pb
Form: Foil/Film/Sheet
Material: Lead
CAS Number: 7439-92-1
Commodity: Metals
Goodfellow provides lead foil with a maximum purity of 99.999% (5N). Despite environmental concerns, high-purity lead foil remains crucial in specific applications due to its unique properties. It's extensively used in radiation shielding for medical and nuclear applications, benefiting from lead's high density. In the electronics industry, lead foil is used in specialized solders and as a protective layer in certain battery technologies. For research purposes, ultra-pure lead foil is valuable in studying superconductivity and in the development of advanced radiation detection systems. Its role in particle physics experiments and specialized imaging technologies highlights its ongoing importance in scientific research. The foil's high purity ensures minimal interference in sensitive measurements, making it ideal for use in experiments requiring both radiation protection and precise elemental composition.
