摘要

采用固相法合成了稀土元素M10W22O81多钨酸盐（M = La, Nd, Ce）；研究了它们的热和电输运性质。用电化学阻抗法测定了电导率随气相温度和氧压的变化规律。三种方法（电导率作为氧压的函数的测量，电动势方法的输运数测量和Tubandt方法）的组合表明所研究的多钨酸盐是氧离子导体。

Synthesis and Study of Electrical Transport Properties of Rare Earth Polytungstates M10W22O81 (M = La, Nd)

The polytungstates of rare earth elements M₁₀W₂₂O₈₁ (M = La, Nd, Ce) were synthesized by a solid-phase method; their thermal and electrical-transport properties were studied. The electrical conductivity depending on the temperature and oxygen pressure in the gas phase was measured by the electrochemical impedance method. A combination of three methods (the measurements of electrical conductivity as a function of oxygen pressure, the transport number measurements by the EMF method, and the Tubandt method) showed the studied polytungstates to be oxygen-ion conductors.
