| 7 | Facile fabrication of cordierite-based porous ceramics with magnetic properties显示文摘In this paper,cordierite-based porous ceramics with magnetic properties have been firstly in-situ synthesized by using MgO,Al_(2)O_(3),and SiO_(2) powders as raw materials and Fe_(3)O_(4) as a functional additive.Combining with the foam freeze casting method,near net size fabrication(total linear shrinkage<2.86%)of the magnetic porous materials was realized by adjusting the amount of Fe_(3)O_(4).The porosity,compressive strength,and saturation magnetization of the prepared materials were 83.9%-87.8%,1.51-2.65 MPa,and 1.2-5.8 emu/g,respectively.The phase composition and microstructure evolutions during sintering were investigated briefly.The results showed that the synthesis temperature of cordierite was lowered about 100℃ due to the addition of Fe_(3)O_(4).Except for the main phase-cordierite,Mg-Al-Fe spinel and α-Fe_(2)O_(3) also existed in the final materials.The lattice parameters of the Mg-Al-Fe spinel and the amount of α-Fe_(2)O_(3) changed obviously with the change in the sintering temperature and Fe_(3)O_(4) amount,which mainly influenced the magnetic properties of the prepared materials.Thus,a facile fabrication method of the cordierite-based porous ceramics with the magnetic properties has been put forward in this paper. | Hao LI Cuiwei LI Huaiming JIA Guangjin CHEN Siyuan LI Kepi CHEN Chang-An WANG Liang QIAO | 2022 | Journal of Advanced Ceramics2022，11，10： | 0 |

| 9 | Ca^2+ doping effects in(K,Na,Li)(Nb0.8Ta0.2)O3 lead-free piezoelectric ceramics显示文摘Lead-free(K0.5-x/2Na0.5-x/2Lix)(Nb0.8Ta0.2)O3(KNLNT)and(K0.49-x/2Na0.49-x/2-LixCa0.01)(Nb0.8Ta0.2)O3(KNLNT-Ca)ceramics were prepared by a conventional ceramic processing.Structural analysis shows that the Ca^2+ doping takes the A site of ABO3 perovskite and decreases the phase transition temperature.Property measurements reveal that as a donor dopant,the Ca^2+ doping results in higher room-temperature dielectric constant,lower dielectric loss,and lower mechanical quality factor.In addition,the Ca^2+ doping does not change the positive piezoelectric coefficient d33,but increases the converse piezoelectric coefficient d 33*significantly.This is likely due to the increase in the relaxation,as well as the appearance of(CaNa/K·-VNa/K’)defect dipoles. | Lei TANG Tengfei LIU Jinxu MA Xiaowen ZHANG Linan AN Kepi CHEN | 2019 | Frontiers of Materials Science2019，13，4： | 0 |
