在改进的带式装置中通过高压反应获得了SrVO_3、Sr_2VO_4和Sr_3V_2O_7的单晶。晶体结构由衍射数据修正如下：SrVO_3，钙钛矿型，Pm_3·m，a = 3.8408（3）Sr，R = 0.017，Rw = 0.018，氧位占位修正组成SrVO_2.93（2）; Sr2VO4，K2NiF4型，I 4/mmm，a = 3.837（1），c = 12.569（1）Ω，R = 0.014，Rw = 0.017; Sr3V2O7，Sr3Ti2O7型，I 4/mmm，a = 3.839（1），c = 20.262（2）Ω，R = 0.020，Rw = 0.029。
Single crystals of SrVO3, Sr2VO4 and Sr3V2O7 have been obtained by high-pressure reactions in a modified belt-type apparatus. The crystal structures, refined from diffractometer data, are as follows: SrVO3, perovskite type, Pm3̄m, a = 3.8408(3) Å, R = 0.017, Rw = 0.018, composition from occupancy refinement of oxygen positions SrVO2.93(2); Sr2VO4, K2NiF4 type, I 4/mmm, a = 3.837(1), c = 12.569(1) Å, R = 0.014, Rw = 0.017; Sr3V2O7, Sr3Ti2O7 type, I 4/mmm, a = 3.839(1), c = 20.262(2) Å, R = 0.020, Rw = 0.029.
