Zinc alloys have been used for centuries, although A. Marggraf is credited for the first isolation of zinc from the charcoal reduction of calamine in 1746. This bluish-white metal is brittle at ambient temperatures but becomes malleable between 110 °C – 150 °C. It is an essential element in
the growth of plants and animals, and altered biological concentrations of zinc can lead to severe health problems. Zinc’s principle use is to galvanize iron and steel, preventing corrosion. It is also used to form numerous metal alloys such as brass, bronze, and aluminum solder. Zinc oxide is used in plastics, cosmetics, and wallpaper, while zinc sulfide is employed in luminescent dials, TV screens, and fluorescent lights.
