Samarium Specification

The Samarium is an organic compound with the formula Sm. The IUPAC name of this chemical is samarium. With the CAS registry number 7440-19-9, it is also named as samario. The product's categories are Inorganics; Catalysis and Inorganic Chemistry; Chemical Synthesis; Metals; Samarium; SamariumMetal and Ceramic Science. Besides, it is a silvery grey powder, which should be stored in a cool and dry place.

Preparation: the metal is often prepared by electrolysis of a molten mixture of samarium(III) chloride with sodium chloride or calcium chloride. Samarium can also be obtained by reducing its oxide with lanthanum. The product is then distilled to separate samarium (boiling point 1794 °C) and lanthanum (b. p. 3464 °C).

Uses of Samarium: one of the most important applications of samarium is in samarium-cobalt magnets, which have a nominal composition of SmCo5 or Sm2Co17. They have high permanent magnetization, which is about 10,000 times that of iron and is second only to that of neodymium magnets. However, samarium-based magnets have higher resistance to demagnetization, as they are stable to temperatures above 700 °C. These magnets are found in small motors, headphones, high-end magnetic pickups for guitars and related musical instruments. Another important application of samarium and its compounds is as catalyst and chemical reagent. Samarium catalysts assist decomposition of plastics, dechlorination of pollutants.

When you are using this chemical, please be cautious about it as the following:
It is highly flammable and has danger of cumulative effects. Please keep away from sources of ignition - No smoking. Besides, this chemical contacts with water liberates extremely flammable gases. When you are using it, never add water to this product. Take precautionary measures against static discharges.
