Lead-free antiferroelectric ceramic material with large heat stagnation and strong relaxation as well as preparation method and application of lead-free antiferroelectric ceramic material
The invention discloses a lead-free antiferroelectric ceramic material with large heat stagnation and strong relaxation, the stoichiometric formula of the lead-free antiferroelectric ceramic material is (1-x) NaNbO3-xBi2/3SnO3, and the preparation method of the ceramic material comprises the following steps: adding Bi2/3SnO3 into NaNbO3, and carrying out ball milling, drying, briquetting, sieving, isostatic cool pressing and sintering to obtain a (1-x) NaNbO3-xBi2/3SnO3 ceramic sample so as to improve the maximum heat stagnation and relaxation of the ceramic material. The (1-x) NaNbO3-xBi2/3SnO3 ceramic material provided by the invention is simple in preparation process, convenient to operate, low in material cost, green and environment-friendly, and suitable for preparation and application of a ceramic capacitor and a dielectric capacitor in a high-power pulse system.
本发明公开了一种具有大热滞强弛豫的无铅反铁电陶瓷材料，其化学计量式为(1‑x)NaNbO3‑xBi2/3SnO3，该陶瓷材料的制备方法包括，将Bi2/3SnO3添加到NaNbO3中，通过球磨、烘干、压块、过筛、冷等静压、烧结得到(1‑x)NaNbO3‑xBi2/3SnO3陶瓷样品，以提高陶瓷材料的最大热滞和弛豫。本发明提供的(1‑x)NaNbO3‑xBi2/3SnO3陶瓷材料制备工艺简单，操作方便，材料成本低，绿色环保，适用于陶瓷电容器以及高功率脉冲系统中介质电容器的制备和应用。
