Lead Sputtering Target

Lead is a chemical element with atomic number 82 and symbol Pb (from the Latin plumbum). It is a heavy metal with a density exceeding that of most common materials; it is soft, malleable, and melts at a relatively low temperature. When freshly cut, it has a bluish-white tint; it tarnishes to a dull gray upon exposure to air. Lead has the second-highest atomic number of the classically stable elements and lies at the end of three major decay chains of heavier elements.

Lead Sputtering Target Information

Lead Sputtering Targets
Purity is 99.995%;
Circular: Diameter <= 14inch, Thickness >= 1mm;
Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm.
This material may require special ramp up and ramp down procedures. This process may not be necessary with other materials. Targets that have a low thermal conductivity are susceptible to thermal shock.
