High-throughput preparation method of bismuth ferrite-barium titanate based leadless piezoelectric ceramic
The invention discloses a high-throughput preparation method of bismuth ferrite-barium titanate-based leadless piezoelectric ceramics, which comprises the following steps: by taking Fe2O3, Bi2O3, BaTiO3 and a doped element compound as raw materials, carrying out ball-milling mixing, drying, tabletting and the like to prepare a ceramic sample green body; placing the sample green bodies in a muffle furnace for glue discharging and roasting, and alternately stacking a plurality of ceramic sample green bodies in a quartz tube by taking zirconium oxide balls or sheets as supporting pads; and sintering the quartz tube in a vertical tube furnace with gradient temperature, thereby completing one-time high-throughput preparation of a plurality of ceramic samples at different sintering temperatures. Compared with a traditional preparation process, the method has the advantages that the required period is short, the time is short, the energy consumption is reduced, and higher ceramic sample preparation efficiency can be achieved under the same volume; compared with other high-throughput methods, the method has the advantages of low equipment cost and simple principle. And the bismuth ferrite-barium titanate-based leadless piezoelectric ceramic with optimal components, sintering temperature and electrical properties can be rapidly screened out at one time in a relatively large temperature range.
本发明公开了一种铁酸铋‑钛酸钡基无铅压电陶瓷的高通量制备方法，以Fe2O3、Bi2O3和BaTiO3和掺杂元素化合物为原料，先经球磨混料、烘干、压片等步骤制备陶瓷样品坯体。再将样品坯体放入马弗炉排胶并焙烧，随后以氧化锆球或片为支垫，将多个陶瓷样品坯体相间叠放在石英管中。将石英管放入具有梯度温度的立式管式炉内烧结，即可完成多个陶瓷样品在不同烧结温度下的一次性高通量制备。本发明方法相比于传统制备工艺，所需周期少、时间短，节约能耗，同样大小容积下可以达到更高的陶瓷样品制备效率；相较于其它高通量方法使用的设备成本低、原理简单。在较大温度范围内一次性快速筛选出最佳的成分、烧结温度以及电学性能的铁酸铋‑钛酸钡基无铅压电陶瓷。
