Lead (Pb)
Known as one of the oldest metals, native lead rarely occurs naturally. The most common lead-containing minerals are galena, anglesite, cerussite, and minim.
Lead is shiny, bluish-white, and very soft. It's highly malleable, ductile, and conducts electricity poorly. Natural lead is a mixture of four stable isotopes, all from the decay of naturally occurring radioactive elements.
The metal is used in solder, cable covering, plumbing, and ammunition, and as a radiation shield for X-ray equipment and nuclear reactors. Lead compounds are used in batteries, paints, crystal, and flint glass. It's also a cumulative poison and must be handled with care.

Electron Microscopy Sciences Beryllium Support Film, 25x25 mm
A beryllium support film will reduce background interference for microanalysis to a minimum. It is particularly useful where analyses for Carbon or silicon are required and supports contain these elements cannot be used.
A deposition of 250 Angstroms thick Beryllium onto the 0.005" thick, 25x25 mm squares of a Cu substrate. The Be can be removed by dissolving the substrate in nitric acid (50:50). The Be film will then be removed from the acid, washed in distilled water and mounted on TEM grids.
Be support film is its very fine grain size which produces a very sharp ring pattern that can be used for in-situ calibration.
