摘要

在氧化物Bi/sub - 1.5/ZnNb/sub - 1.5/O/sub - 7/ 7/中以氟取代氧得到的固溶体Bi/sub - 1.5/(Zn/sub - 1-x/Li/sub -x/)Nb/sub - 1.5/(O/sub - 7-x/F/sub -x/)的结构为立方烧氯，为0/spl les/x/spl les/0.15。当x值为0.80/spl les/x/spl les/1.00时，会产生对称性较低的畸变修正，而当x值在0.15 ~ 0.80之间时，则会形成上述两者的混合相。研究了介电常数的温度依赖性，并观察到低温(小于100/spl℃)下的介电异常。

The structure and dielectric properties of new oxyfluorides

The structure of solid solution Bi/sub 1.5/(Zn/sub 1-x/Li/sub x/)Nb/sub 1.5/(O/sub 7-x/F/sub x/) obtained by substitution of oxygen by fluorine in the oxide Bi/sub 1.5/ZnNb/sub 1.5/O/sub 7/ is cubic pyrochlore for 0/spl les/x/spl les/0.15. For 0.80/spl les/x/spl les/1.00, a distorted modification with low symmetry results, while the mixed phases of the above two are formed for other values of x between 0.15 and 0.80. The temperature dependences of the dielectric constants have been studied, and a dielectric anomaly at low temperatures (less than 100/spl deg/C) has been observed.
