【摘要】 用共沉淀法合成了BaTiO3,研究了Ba1-xNdxTiO3系Nd3+施主一次掺杂在x=0.03~0.065之间时,BaTiO3基陶瓷电容器的本征电性能。结果表明,在此含量范围掺杂的情况下,陶瓷呈绝缘性,Nd3+含量在0.03~0.055左右时随着Nd3+含量的增加,陶瓷的ε增加,Tc呈下降趋势,tgδ值下降。Zr4+的加入也可使材料的ε增加,Tc下降。Mn2+的加入对材料的本征电性能影响不大。Ba1-3x/2NdxTiO3配比比Ba1-xNdxTiO3配比的材料的温度特性要好。更多还原

【Abstract】 Nd³⁺ doped BaTiO₃ was synthesized by precipitation,and the electrical properties of BaTiO₃ ceramic of Ba_1-xNd_xTiO₃ with different concentration（x from 0.03 to 0.065） were investigated.Experimental results showed that BaTiO₃ ceramic acted as insulator when Nd³⁺ was in the range of 3.0 6.5 mol%.In the range of 0.03 0.055,the(value of BaTiO₃ ceramic was increased as concentration enhanced,but the Tc and tg δ were decreased.The(value also decreased when added with Zr⁴⁺,whereas there was no difference when added with Mn²⁺.更多还原
