一种可提高MTiO3陶瓷挠曲电响应的烧结制备方法
本发明公开一种可提高MTiO3陶瓷挠曲电响应的烧结制备方法，M为Ba和/或Sr，包括以下步骤：将MCO3和TiO2分别按MTiO3化学计量称量，混合，以乙醇为溶剂进行第一次球磨，烘干，在1100～1299℃下保温1～4h合成，得到第一次煅烧后的陶瓷块体；将所述陶瓷块体粉碎后，以乙醇为溶剂进行第二次球磨，第二次球磨后的浆料干燥后加入粘结剂，压制成型，之后在700～900℃下保温1～4h，得到排塑完成的MTiO3陶瓷坯体；将排塑完成的MTiO3陶瓷坯体放入管式炉，在H2和N2的混合气氛下，以0.1～15℃/min的速率升温至1200～1400℃保温1～4h，之后以0.1～30℃/min的速率降温至室温；得到直接还原烧结的MTiO3。
The invention discloses a sintering preparation method capable of improving flexoelectric response of MTiO3 ceramic, M is Ba and/or Sr. The sintering preparation method comprises the following steps: respectively weighing and mixing MCO3 and TiO2 according to stoichiometric measurement of MTiO3, carrying out first-time ball milling and drying by taking ethanol as a solvent, and carrying out heat preservation at 1100-1299 DEG C for 1-4 hours for synthesis to obtain a ceramic block subjected to first-time calcination; crushing the ceramic block, carrying out secondary ball milling by taking ethanol as a solvent, drying slurry subjected to the secondary ball milling, adding a binder, carrying out compression molding, and then carrying out heat preservation at 700-900 DEG C for 1-4 hours to obtain an MTiO3 ceramic green body subjected to plastic removal; putting the MTiO3 ceramic green body subjected to plastic removal into a tubular furnace, heating to 1200-1400 DEG C at a rate of 0.1-15 DEG C/min in a mixed atmosphere of H2 and N2, keeping the temperature for 1-4 hours, and then cooling to room temperature at a rate of 0.1-30 DEG C/min; the directly reduced and sintered MTiO3 is obtained.
