What is Samarium?
- Samarium is a chemical element with atomic number 62 and is represented by the symbol Sm in the Periodic Table.
- It was discovered by Paul Emile Lecoq de Boisbaudran in the year 1879.
Uses of Samarium
- The most important application of Samarium is in Samarium-Cobalt magnets which have a very high permanent magnetisation. These magnets are used in headphones, small motors and musical instruments like guitars.
- This element is used in the manufacture of solar-powered electric aircraft.
- It is used in making special infrared absorbing glass and cores of carbon arc lamp electrodes.
- Acts as a catalyst in the ethanol dehydration process. It is also used in making new permanent magnets.
Properties of Samarium
- It is a silvery-white, rare earth metal having physical properties like hardness, similar to zinc.
- It is one of the most volatile elements among Lanthanides.
- Samarium and its compounds are paramagnetic at room temperature.
- It is the 40th most abundant element in earth’s crust and the 5th most abundant element among Lanthanides.
- This element is most abundant in China, India, Brazil, the US, Australia and Sri Lanka and yearly production is estimated at 2 million tonnes.
Certain Health Facts About Samarium
- Samarium has no biological role and it is not that toxic. It is observed that some soluble salts are mildly toxic but cannot affect human life.
