Samarium Boride SmB6 CAS 12008-30-9 For Chemical Valence Fluctuation

 

Name: Samarium boride, Samarium hexaboride                                Molecular formula: SmB6

 

CAS: 12008-30-9                                                                                Molecular weight: 215.22

 

Description: Samarium hexaborate is a black powder, which is difficult to dissolve in water and hydrochloric acid. At present, the preparation of samarium hexaborate is generally by boron carbide thermal reduction method, and the reaction formula is Sm2O3 + 3B4C--2SmB6 + 3CO; because of the introduction of boron carbide as the reaction raw material, the carbon content of the product is difficult to control, and because of the high hardness and large particle size of boron carbide, it is easy to produce the phenomenon of uneven mixture, which makes the chemical composition of the product deviate. Samarium hexaboride is an intermediate-valence compound where samarium is present both as Sm2+ and Sm3+ ions at the ratio 3:7. It belongs to a class of Kondo insulators. New research seems to show that it may be a topological insulator.

Uses: Its electrical resistance indicates that the material behaves as an insulator; however, its Fermi surface (an abstract boundary used to reliably predict the properties of materials) contradicts this, indicating that the material actually behaves as a good metal. At temperatures approaching absolute zero, the quantum oscillations of the material grow as the temperature declines, a behavior that contradicts both the Fermi analysis and the rules that govern conventional metals.
