EC No.	215-222-5
CAS No.	1314-13-2
Structural Formula	Zn=O

ZnO occurs as white powder known as zinc white or as the mineral zincite. The mineral usually contains a certain amount of manganese and other elements and is of yellow to red color. Crystalline zinc oxide is thermochromic, changing from white to yellow when heated and in air reverting to white on cooling.

The applications of zinc oxide powder are numerous, and the principal ones are summarized below. Most applications exploit the reactivity of the oxide as a precursor to other zinc compounds.

	RUBBER : Heavy-duty pneumatic tires carry high loadings of Zinc Oxide for heat conductivity as well as reinforcement since heat-buildup is critical at their higher operating speeds compared with their solid-rubber counterparts. It is mainly used for activation, acceleration, biochemical activity, heat stabilization, latex geletion, etc.
	PAINT: Zinc Oxide in organic coatings provides a broad spectrum of properties: optical, chemical, biochemical and physical.
	CERAMICS : Zinc Oxide imparts a unique combination of properties when used in glass. Zinc Oxide reduces the coefficient of thermal expansion, imparts high brilliance and luster and high stability against deformation under stress.
	PHARMACEUTICAL INDUSTRY : Zinc Oxide is mainly used in Zinc soap, ointment, dental inlays, food powders etc. Zinc Oxide forms an indispensable element of the production process of this industry.
	COSMETICS : The optical and biochemical properties of Zinc Oxide and its derivatives impart special features to a variety of cosmetic preparations for care of the hair and skin.
	FOOD INDUSTRY : Zinc Oxide and its derivatives contributing special fungi-static and chemical properties to the processing and packaging of various animal and vegetable products.
	OTHERS : Zinc oxide is also used as fire retardants, in ferrites, in batteries,fuel cells,photo cells, as thermoelements ,silicate compositions, in sulphur removal, as metal protective coating, etc.
