Abstract

The phase behavior of monoclinic (B-type) Eu₂O₃ under pressure in a diamond anvil cell was studied at room temperature by energy-dispersive X-ray diffraction at the Cornell High Energy Synchrotron Source. The bulk modulus (B₀) of B-type Eu₂O₃, derived from the compression curve obtained, was 140 GPa. A pressure-induced phase transition from the monoclinic to the hexagonal (A-type) crystal structure was observed at about 4.7 GPa. The fractional volume change, ΔV/V, under this transition pressure was approximately -2%.
