Nb3Sn and SmCo5 are two important intermetallic compounds. Nb3Sn is a superconductor
Chapter 23, Problem 23.4(choose chapter or problem)
Nb3Sn and SmCo5 are two important intermetallic compounds. Nb3Sn is a superconductor from which the electromagnets of a magnetic resonance imaging (MRI) instrument are built, while SmCo5 is used to make powerful permanent magnets. The unit cells of Nb3Sn and SmCos are shown below. By counting the atoms in the unit cell, determine the empirical formulas corresponding to each structure. Then use this information to determine which structure corresponds to which intermetallic compound. (Hint: In both structures all of the atoms shown are located either at the comers of the unit cell, the body center of the unit cell, or the faces of the unit cell.) [Section 23.6]
