| 摘 要： | 利用酸蒸气水热法合成了Zr(WMo)1-x/2VxO7-x/2(OH)2·2H2O(x=0.04,0.08,0.10,0.14,0.20,0.22,0.26,0.32)四方晶相固溶体。以此为前驱体,通过高温脱水和相转变法合成了立方相Zr(WMo)1-x/2VxO8-x/2(x=0.04,0.08,0.10,0.14,0.20,0.22)固溶体。立方Zr(WMo)1-x/2VxO8-x/2固溶体具有Pa3空间群。Zr(WMo)1-x/2VxO8-x/2的平均晶体结构描述为按照化学计量的ZrV2O7结构与β-ZrWMoO8结构的叠加。ZrV2O7在立方ZrWMoO8中的固溶度为11mol%;立方Zr(WMo)1-x/2VxO8-x/2固溶体的相变温度低于200 K;在200 K～573 K温度范围内具有负热膨胀系数;线热膨胀系数近似为常数。
