摘要：
The synthesized monoclinic (B-type) phase of Y2O3 has been investigated by in situ angle-dispersive x-ray diffraction in a diamond anvil cell up to 44 GPa at room temperature. A phase transition occurs from monoclinic (B-type) to hexagonal (A-type) phase at 23.5 GPa and these two phases coexist even at the highest pressure. Parameters of isothermal equation of state are V-0 = 69.0 (1) angstrom(3), K-0 = 159 (3) GPa, K'(0) = 4 (fixed) for the B-type phase and V-0 = 67.8(2) angstrom(3), K-0 = 156 (3) GPa, K'(0) = 4 (fixed) for the A-type phase. The structural anisotropy increases with increasing pressure for both phases.
