2 Facts
2.1 Interesting Facts
- Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
- After iron, Zinc metal the second most abundant element in the earth crust.
- Barium oxidizes very easily in the air.
- All toxic compounds of Barium can easily dissolve in water.
- Barium carbonate is used to produce a Rat poison and its other compound Barium nitrate is used in fireworks to produce green color.

4 Uses
4.1 Uses & Benefits
- It has corrosion resistance and hence it is used to plate other metals.
- Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
- It is sued in chemical paint manufacturing and glass manufacturing.
-
Compounds of this metal are toxic; but still the barium sulfate is insoluble and given to patients suffering from digestive disorder.
