研究了0.375 Pb (Ni 1/3 Nb 2/3) O 3 - 0.25 PbZrO 3 - 0.375 pbtio3的低温烧结性能。将高纯NiO、Nb 2o、PbO、TiO 2、ZrO 2原料粉混合，平均研磨至0.2µm， 850℃煅烧2 h，得到无焦氯化物的煅烧粉，再次焙烧，最后在925℃下烧结4 h，不添加烧结助剂。烧结后的试样相对密度为99%，机电耦合因子平面模态kp = 0.61，压电常数d33 = 600 pm/V，居里温度T c= 189 c，制备了纯银内电极多层致动器。
Low-temperature sintering of 0.375 Pb (Ni 1/3 Nb 2/3) O 3–0.25 PbZrO 3–0.375 PbTiO 3 was investigated. Raw material powders of high-purity NiO, Nb 2 O 5, PbO, TiO 2, and ZrO 2 were mixed and ground to 0.2 µm on average, calcined at 850 C for 2 h to obtain pyrochlore-free calcined powder, ground again, and finally sintered at 925 C for 4 h, without adding sintering additives. The sintered sample showed a relative density= 99%, an electromechanical coupling factor planar mode k p= 0.61, a piezoelectric constant d 33= 600 pm/V, and a Curie temperature T c= 189 C. Accordingly, a multilayered actuator with pure Ag internal electrodes was prepared using the calcined powder.
