2.  Zinc is a chemical element which is denoted by symbol Zn. Zinc is the 30th element on the periodic table, and has an atomic number of 30. Zinc has a mass number of 65.38.  Zinc dust is powdery metallic zinc usually containing zinc oxide in varying amounts that collects as a bluish gray powder during distillation of zinc and that is used as a reducing agent.

3.  Zinc is a shiny bluish grey metal.  When it has just been cut, zinc has a whitish-grey color.  Its melting point is 419.58 °C & 787.24 °F.  Its boiling point is 907.0 °C & 1,664.6 °F.  It forms alloys easily with other metals.

4.  Zinc is a reactive metal.  It is about as reactive as aluminium and more reactive than most of the more common metals, such as iron, copper, nickel, and chrome.  Zinc can react with acids, bases, and non-metals.  A coating of zinc oxide and zinc carbonate forms on the surface of the zinc when it is in air.

5. Zinc is used as a metal:- Zinc is used in electrical batteries. It becomes oxidized and provides electrons for the battery to run. About 59% of zinc is used for corrosion prevention, which includes galvanizing. This is used to protect another metal, usually iron, from rusting. Zinc is used in alloys. Brass is the most common zinc alloy. Zinc can be used in the pipes of a pipe organ.

6. Zinc is used as zinc compounds:- About 1/4 of zinc is used to make zinc compounds. Zinc oxide can be used for sunscreen or paint pigment. Zinc chloride is used to preserve wood so it does not rot. Zinc sulfate is used in dyes and pigments. Zinc sulfide is used in fluorescent bulbs to convert the ultraviolet light to visible light.

7. Zinc Dust is very useful in today’s world. As we have a big problem of rusting in metals and it can be solved by the use of Zinc Dust. Zinc Dust is a pure metal powder, which is used to protect the metal from corrosion. It is suitable for use in many formulations for the manufacture of zinc primers and shop primers.
