✦ Synopsis

The compound Sm7Zr4Co89 is observed in the 1150 • C isothermal section of the Sm-Co-Zr system and its structure is studied by powder XRD. The compound has the hexagonal Sm2Co17 or Th2Ni17 type structure with a statistical substitution of Zr for Sm. The stabilization of the hexagonal structure is explained in terms of the ratio of the Sm, Zr, and Co atom radii.
