High-pressure phase transformation in scandium

Academic Article


  • The 3d transition metal scandium (Sc) has been studied under pressures up to 35 GPa by energy-dispersive x-ray diffraction. A structural phase transition was observed around 20 GPa from hcp to β-Np structure (tetragonal, four atoms per unit cell). This high-pressure structure of Sc is different from any known structure of trivalent rare-earth metals and points out the limitations of canonical band-theory calculations which qualitatively accounted so far for the crystal-structure trends in the d-band metals, including lanthanides. © 1982 The American Physical Society.
