摘要：

High-pressure behavior of Sr-3(VO4)(2) and Ba-3(VO4)(2) is investigated with energy-dispersive X-ray diffraction up to 27.0 and 29.0 GPa, respectively. For Sr-3(VO4)(2) (R (3) over bar m); there occurs a phase transition to an orthorhombic structure in the 13.8-17.0 GPa pressure range. Ba-3(VO4)(2) (R (3) over bar m) does not undergo any structural transformation up to 29.0 GPa. The systematic high pressure behavior in the Ca-3(VO4)(2) (R3c), Sr-3(VO4)(2), and Ba-3(VO4)(2) series is discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
