4N5 (99.995%) Lead (Pb) Pieces Evaporation Materials

Lead (Pb) is a heavy metal that is denser than most common materials. It is soft and malleable and has a relatively low melting point. When freshly cut, lead is bluish-white; it tarnishes a dull gray color when exposed to air. It has the highest atomic number of any stable element and concludes three major decay chains of heavier elements. Lead-based semiconductors such as lead telluride and lead selenide are widely used in photovoltaic cells and infrared detectors.
