Barium titanate-based high-entropy lead-free relaxor ferroelectric energy storage ceramic and preparation method thereof
The invention discloses barium titanate-based high-entropy lead-free relaxor ferroelectric energy storage ceramic and a preparation method thereof. The preparation method comprises the following steps: mixing the components, mixing with ethanol and zirconium balls, carrying out primary ball milling, drying after ball milling, presintering at 750-950 DEG C, and then carrying out ball milling and drying treatment to obtain powder; the barium titanate-based high-entropy lead-free relaxor ferroelectric energy storage ceramic can be obtained by carrying out ball milling on the barium titanate-based high-entropy lead-free relaxor ferroelectric powder, tabletting and forming the ball-milled powder and sintering the formed green body at 1000-1250 DEG C. Compared with the traditional high-temperature sintering, the barium titanate-based high-entropy lead-free relaxor ferroelectric energy storage ceramic has the advantages that the low-temperature efficient sintering process at 1000-1250 DEG C is adopted, so that the sample preparation time is greatly shortened, and the sample sintering temperature is reduced. The barium titanate-based high-entropy lead-free relaxor ferroelectric energy storage ceramic sample prepared by the method can be highly densified, and the energy storage performance and the energy storage density of the sample are synergistically improved.
本发明公开了一种钛酸钡基高熵无铅弛豫铁电体储能陶瓷及其制备方法，通过上述组分混合后与乙醇、锆球混合，进行初次球磨，球磨后进行干燥在750‑950℃预烧，然后进行球磨并干燥处理得到粉体；将球磨后的粉体进行压片成型，成型后的生坯在1000‑1250℃下进行烧结，即可得到钛酸钡基高熵无铅弛豫铁电体储能陶瓷，采用1000‑1250℃的低温高效烧结工艺，较于传统的高温烧结大大缩短了样品制备的时间以及降低了样品烧结的温度。且本发明所述方法制备的钛酸钡基高熵无铅弛豫铁电体储能陶瓷样品可达到高度致密化，样品的储能性能和储能密度获得协同提升。
