AbstractA body-centered orthorhombic structure is proposed for the high-pressure phase of tellurium which has been observed between 40 kbar and 70 kbar. This structure is based on the in situ data of others using high-pressure x-ray diffraction. The proposed structure is in agreement with density data, and appears related to a distorted
Here, we have discovered a new high-pressure phase of Sb2O3, and reported pressure-induced anomalies in orthorhombic β-Sb2O3 (valentinite) by the combination of synchrotron in situ X-ray diffraction and first-principles theoretical calculations up to 40.5 GPa.
