چکیده انگلیسی
Y3+ and Fe3+ co-doped BaZr0.13Ti1.46O3 powders were synthesized by wet chemical method through a precipitation process, able to control uniformity and particle size of the BaZr0.13Ti1.46O3-based particles. Fine-grained BaZr0.13Ti1.46O3 ceramics co-doped with various amounts of Y3+ and Fe3+ were prepared at low sintering temperature to yield good dielectric properties and gentle temperature stability. The co-doping effect on the microstructure and dielectric properties of BaZr0.13Ti1.46O3 ceramics were studied. Results showed the dielectric constants firstly to increase monotonically then decrease with the increase of Y3+ and Fe3+concentration. Overall, the resulting ceramics met the X8R specification when Y3+ and Fe3+ contents were 2 or 4Â mol%. Moreover, the increase in Y3+ and Fe3+ doping concentration from 6 to 8Â mol% satisfied the X7R specification.
