Abstract

The traditional solid-state synthesizing method was employed to prepare Tl_5-xK_xLuZr(MoO₄)₆ (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 Tl_5-xK_xLuZr(MoO₄)₆ (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. Tl_4.9K_0.1LuZr(MoO₄)₆ has the best ionic conductivity of this series of molybdates (1.31 × 10⁻³ S cm⁻¹₎, and Tl₅LuZr(MoO₄)₆ has the lowest conductivity (5.51 × 10⁻⁴ S cm⁻¹₎. Activation energy was found out to decrease from 1.32 eV for Tl₅LuZr(MoO₄)₆ to 0.92 eV for Tl_4.9K_0.1LuZr(MoO₄)_6.

新型 Tl5-xKxLuZr(MoO4)6 (x = 0; 0.1; 0.2; 1; 2) 钼酸盐的合成及其结构、热学和电学特性研究

采用传统固态合成法制备了 Tl5-xKxLuZr(MoO4)6 (x = 0; 0.1; 0.2; 1; 2) 陶瓷。通过对 X 射线粉末衍射数据的里特维尔德法进行了结构表征。确定了 Tl5-xKxLuZr(MoO4)6 (x = 0; 0.1; 0.2; 1; 2) 的单胞参数。在 300 至 800 K 的温度范围内测量了阻抗谱，频率范围为 1 Hz 至 1 MHz。结果表明，在 x = 0.1-2.0 的范围内，电导率随着 x 值的增加而降低。在这一系列钼酸盐中，Tl4.9K0.1LuZr(MoO4)6 的离子导电率最好（1.31 × 10-3 S cm-1），而 Tl5LuZr(MoO4)6 的导电率最低（5.51 × 10-4 S cm-1）。活化能从 Tl5LuZr(MoO4)6 的 1.32 eV 下降到 Tl4.9K0.1LuZr(MoO4)6 的 0.92 eV。
