 Zinc & Compounds 

Atomic Number:         30           Period Number: 4                Group Number: 12


Zinc, which is a bluish-white metal, ranks as the 24th most abundant element found in the earth's crust. The main sources of zinc ore is sphalerite. There are five stable isotopes of Zinc in nature: 64Zn, 66Zn, 67Zn, 68Zn, 70Zn.

Zinc  oxide can be used for semiconductors, as additives in rubber to prevent fungi growth and block UV light, to improve processing time and water resistance of concrete, in cigarette filters, as food additives, in pigments and anti-corrosive coatings, for medical purposes and in cosmetic products which help block UV rays, and in ceramics and glass compositions.

Zinc Oxide (ZnO) affectionately known as Zinc White, has been used as a mineral since antiquity when it was melted with copper to form brass. As was true hundreds of years ago, zinc oxide is commonly used as a medical ointment today. Sources differ on who first isolated the element but historians largely agree that zinc oxide was suggested as a white pigment around 1782. Regardless of defined history the early adaptations of zinc oxide has transcended to its current uses in semiconductors, concrete, ceramic and glass composition and even cigarette filters.

ZnSe is a light yellow colored compound and is widely used in II-VI light-emitting diodes and diode lasers, infrared laser gain medium, optical materials and scintillators. For these applications, normally high purity ZnSe is used.
