摘要
Abstract
BaZr0.1Ti0.9O3(BZT)+xGd2O3(0≤x≤0.7%) ceramics were prepared by solid state method at the temperature of 1 250, 1 280, 1 300, 1 330℃, respectively. Barium carbonate, zirconium dioxide, titanium dioxide were used as main raw materials, and gadolinium oxide was used as the dopant. X-ray diffraction results reveal that the main crystal phase of the ceramic sample with the Gd3+ doping doesn’t make any change, which is still the perovskite structure. SEM observation shows that, with the increase of Gd2O3 addition, the grain size of the ceramic decreases firstly, and then increases. Whenx=0.2%, 0.6%, the volume density and permittivity appear a higher value and the dielectric loss shows a trend of decreasing. Gd2O3 doping can improve the dielectric temperature change rate of the BZT ceramics.关键词
