1. Zinc Dust

2. Introduction Zinc is a chemical element with symbol Zn. Zinc is first element in group 12 of periodic table. Zinc is 24 th most abundant element in Earth’s crust.

3. Physical Properties Zinc is a bluish-white, lustrous metal. Zinc has a hexagonal crystal structure. Zinc is a fair conductor of electricity.

4. Uses Of Zinc CHEMICAL & PHARMACEUTICAL INDUSTRY PAINTS & COATINGS COSMETICS CASTING BATTERIES

5. CHEMICAL & PHARMACEUTICAL INDUSTRY To form various chemicals, the manufacturers use Zinc Phosphide with various other compounds. They also refine Zinc at the time of manufacturing through electrolytic process. They apply zinc for nitrobenzene production and as catalyst and polymerizing element. Thus, Zinc Dust plays an important role in manufacturing drugs.

6. PAINTS & COATINGS Zinc Dust can prevent steel surfaces from rusting. Zinc Dust can provide a heavy-duty coating for large-scale structures such as offshore oil rigs, sea containers and other marine equipment. Zinc Powder can also be used on bridges. Coating that has zinc powder works best for the protection of any steel elements from rust issues.

7. COSMETICS Zinc Powder can be found in cosmetics products, including talcum and face powders. Two forms of zinc powder may be used: zinc oxide, which can provide UVA protection and mask pores and blemishes; and zinc stearate, which has adhering properties that enable the powder to stick to the skin.

8. CASTING Zinc alloys may be used for casting dies, permanent molds, plaster molds and shell molds. Zinc can be used for creating mixed-metal alloys for foundries.

9. BATTERIES The chemical potential energy in the alkaline batteries for pumping electrical charges between the terminals is due to Zinc Dust. The Dust burns itself up for this purpose and the battery dies when little dust is left.
