The high-pressure and high-temperature behavior of V 2 O 5 with a layered-orthorhombic structure was studied by both in-situ X-ray diffraction observations and recovery experiments. Two quenchable high-pressure phases (HPP1 and HPP2) were observed in the pressure and temperature range up to 11 GPa and 700°C. The phase transition to the HPP1 was observed by elevating the temperature above 300°C in the pressure range up to 7GPa. The HPP1 was found to have an orthorhombic cell (a = 7.100(7) A, b = 6.294(5) A and c = 3.578(2) A at 0.1 MPa and 27°C). The phase transition to the HPP2 was also observed in an elevating temperature process above 9 GPa. Unit cell parameters of the HPP2 have not yet been determined. |
