This work reports the high-pressure and high-temperature (HP-HT)
synthesis of pure rhombohedral (corundum-type) phase of indium oxide (In2O3)
from its most stable polymorph, cubic bixbyite-type In2O3, using a multianvil press.
Structural and vibrational properties of corundum-type In2O3 (rh-In2O3) have been
characterized by means of angle-dispersive powder X-ray diffraction and Raman
scattering measurements at high pressures which have been compared to structural
and lattice dynamics ab initio calculations. The equation of state and the pressure
dependence of the Raman-active modes of the corundum-type phase are reported and
compared to those of corundum (α-Al2O3). It can be concluded that rh-In2O3 is stable
under compression up to 14 GPa and it gradually transforms to the orthorhombic
Rh2O3−III structure with Pbca space group (N. 61) between 14 and 26 GPa. The bulk
modulus, axial compressibilities, and the pressure range of stability of the corundumtype
phase in group IIIA sesquioxides A2O3 (A = Al, Ga, and In) are discussed.
