Samarium Metal Powder Sm CAS 7440-19-9 For Samarium(II) Iodide SmI2

Samarium metal powder, as an important form of rare earth metal samarium, has been widely used in many fields because of its unique physical and chemical properties. Samarium powder is light gray or black metallic luster, with medium hardness, will gradually oxidize in the air, but sealed storage can maintain its stability.
In the field of materials science, samarium powder is a key raw material for the preparation of high-performance permanent magnet materials such as samarium cobalt magnets, which are widely used in electronic devices, automobiles and wind power generation. In addition, samarium powder can also be used as a catalyst to promote the conduct of chemical reactions, especially in the organic synthesis and petrochemical industries.
