摘要：

The traditional solid-state synthesizing method was employed to prepare Tl5-xKxLuZr(MoO4)6 5- x K x LuZr(MoO 4 ) 6 (x x = 0; 0.1; 0.2; 1; 2) ceramics. Structural characterization was performed through the Rietveld method on the X-ray powder diffraction data. The unit cell parameters are defined for Tl5-xKxLuZr(MoO4)6 5- x K x LuZr(MoO 4 ) 6 (x x = 0; 0.1; 0.2; 1; 2). Impedance spectra were measured at temperatures ranging from 300 to 800 K, covering a frequency range of 1 Hz to 1 MHz. The results show that the electrical conductivity decreases with an incrementing in the x value in the range of x = 0.1-2.0. Tl4.9K0.1LuZr(MoO4)6 4.9 K 0.1 LuZr(MoO 4 ) 6 has the best ionic conductivity of this series of molybdates (1.31 x 10-3 S cm-1 ) , and Tl5LuZr(MoO4)6 5 LuZr(MoO 4 ) 6 has the lowest conductivity (5.51 x 10-4 S cm-1 . Activation energy was found out to decrease from 1.32 eV for Tl5LuZr(MoO4)6 5 LuZr(MoO 4 ) 6 to 0.92 eV for Tl4.9K0.1LuZr(MoO4)6. 4.9 K 0.1 LuZr(MoO 4 ) 6.
