The samples with a sintering temperature of 1350 °C and a holding time of 30 min exhibited the most excellent comprehensive performance, with the highest compressive strength and lowest friction......
Effect of Sintering Time on Structure and Properties in CuO-doping KNN-LS-BF Piezoelectric Ceramics王华,ZHAI Xia,XU Jiwen,YANG LingSchool of Materials Science and Engineering, Guilin University... by a solid-state reaction technique, and the structure and piezoelectric properties dependence of sintering time in KNN-LS-BF-CuO ceramics were studied. It is found that all the samples sintered for various......
evolution during the sintering process were examined. The results show that the higher the sintering temperature or the longer the sintering time is, the more the Bi2O3 is volatilized. The heating rate... that the sintering temperature has the greatest impact on the vaporization of the Bi2O3, then followed by sintering time, and the effect of the heating rate is the minimum. Key words: varistor; ZnO; vaporization......
and sintering time. The impedance spectrum measurement results show that both the dielectric constant and dielectric loss have a weak frequency dependence over large frequency region of 50 Hz to 100 kHz, and not only does the dielectric loss decrease but also the dielectric constant remains high sufficiently. The most suitable sintering time is 6 h.Key words:CaCu3Ti4O12 ceramics; dielectric constant......
