Interesting Facts
- The main source of Cobalt is as a by-product of copper and nickel metal mining.
- Cobalt metal can be obtained from other elements like Oxygen, Sulfur and Arsenic.
- It s also used in electroplating process as it exhibits anti cession properties.
- 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.

Uses & Benefits
- Its alloys with aluminum and nickel are used to make powerful magnets.
-
Few other alloys exhibit high-temperature strength and hence they are used in Turbines of Jet and Gas engine.
- 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.
