Interesting Facts
- Yttrium Metal is highly toxic.
- Yttrium Metal is highly reactive in nature hence not found free in nature.
- 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
- Yttrium metal is used in different alloys, as it increases the strength of aluminum Magnesium alloy. It is used for radar microwave filter.
-
It is also used as a catalyst in ethene polymerisation.
- 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.
