Facts
Interesting Facts
  • Magnesium ions are present in every chlorophyll of every green plant .
  • Controlling Magnesium fire by pouring water on it will result in explosions.
  
  • Yttrium Metal is highly toxic.
  • Yttrium Metal is highly reactive in nature hence not found free in nature.

Uses
Uses & Benefits
  • Magnesium aluminum alloy improves the mechanical strength and welding characteristics and hence it is used in aeroplane and car manufacturing.
  • It is also used to remove sulfur from the molten iron and steel.
  
  • 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.
