Abstract:
0.9 {Pb［Zr0.23Ti0.36+0.02(Mg1/2W1/2)+0.39(Ni1/3Nb2/3)］O3}(PZT)/0.1{Ni0.8Co0.1Cu0.1Fe2O4} (NCCF) was successfully prepared by conventional mixed-oxide method. The effects of sintering temperature on the electrical properties and the phase structure were investigated. The results showed that PZT and NCCF kept the respective phase structures, and no new phases were found in the sintered samples. The optimized properties of the ceramics sintered at 1 200 ℃ were obtained, which were listed as follows: d33=317 pC/N, εr=2 593 and tan δ=0.017, which make this system be a good candidate for the memory applications.
