What are samarium physical properties?
Physical properties
Samarium is a yellowish metal with a melting point of 1,072°C (1,962°F) and a boiling point of about 1,900°C (3,450°F). Its density is 7.53 grams per cubic centimeter. Samarium is the hardest and most brittle of the rare earth elements.
What is samarium chemical properties?
Samarium is a silvery-white metal belonging to the lanthanide group of the periodic table. It is relatively stable at room temperature in dry air, but it ignites when heated above 150 C and forms an oxide coating in moist air. Like europium samarium has a relatively stable oxidation state (II).
Does samarium react with water?
Reaction of samarium with water
The silvery white metal samarium is quite electropositive and reacts slowly with cold water and quite quickly with hot water to form samarium hydroxide, Sm(OH)3, and hydrogen gas (H2).
What are samarium uses?
Samarium is used to dope calcium chloride crystals for use in optical lasers. It is also used in infrared absorbing glass and as a neutron absorber in nuclear reactors. Samarium oxide finds specialised use in glass and ceramics.
Does the human body use samarium?
According to researchers, samarium speeds up metabolism. In the human body, the metal is found in the bloodstream, kidneys, and liver. Exposure may cause eye and skin irritation because the salts and compounds are found to be moderately to highly toxic. The metal has been found in some plants and animals as well.
How much is samarium worth per gram?
Samarium costs about $5 per gram, around a third of the price of gold. Samarium's primary use is in samarium cobalt alloy magnets, which are particularly powerful; these are used in consumer applications such as headphones as well as in industrial contexts.

What is the difference between samarium 153 and samarium 149?
- The radioactive isotope samarium-153 is the active component of the drug samarium ( 153 Sm) lexidronam (Quadramet), which kills cancer cells in the treatment of lung cancer, prostate cancer, breast cancer and osteosarcoma. Another isotope, samarium-149, is a strong neutron absorber and is therefore added to the control rods of nuclear reactors.
