采用掺杂Sc2O3,通过固相反应法制备了CaZr1-xScxO3-α (x=0,0.1,0.15)材料.在610-850℃采用交流阻抗谱法测定了CaZr1-xScxO3-α的电导率及电导激活能,并对CaZrO3掺Sc及掺In样品的电学性能进行了比较.结果表明:在610-850℃,CaZrO3的电导率为4.3×10-19-1.4× 10-6S/cm,CaZr1-xScxO3-α(x=0.1,0.15)的电导率为1.16× 10-4-1.4× 10-3S/cm,CaZr1-xInxOa-α (x=0.1,0.15)的电导率为0.34×10-4-4.33×10-4S/cm,且随着温度的升高而提高;掺杂能极大提高CaZrO3的电导率,并随着掺杂量的增加,电导激活能降低,电导率增加;温度及掺杂量相同时,掺Sc材料电导率明显高于掺In材料,说明掺Sc对提高材料的电导率更有效.
