GHS08
Goodfellow supplies lead disks with a maximum purity of 99.999% (5N), catering to specialized applications that require its unique properties. Lead is known for its high density, malleability, and excellent radiation shielding capabilities. While its use is restricted in many consumer products due to toxicity concerns, it remains crucial in certain industries and research fields. Lead is extensively used in radiation shielding for medical and nuclear applications, in the production of lead-acid batteries, and in some specialized alloys. In research, high-purity lead is essential for studying superconductivity, particularly in the development of superconducting magnets. Its role in particle physics experiments and as a target material in nuclear research highlights its ongoing importance in scientific advancement. The continued use of lead in these critical applications underscores its value in both fundamental research and specialized industrial processes.
