一种高击穿的多铁性陶瓷及其制备方法
摘要：
本发明公开了一种高击穿的多铁性陶瓷，其化学计量式为（1-x）BiFeO3-xLaAlO3。本发明还公布了该陶瓷材料的制备方法，将LaAlO3添加到BiFeO3中，通过球磨、烘干、压块、过筛、冷等静压和烧结得到（1-x）BiFeO3-xLaAlO3陶瓷样品。本发明提供的高击穿的（1-x）BiFeO3-xLaAlO3陶瓷材料制备工艺简单，材料成本低，绿色环保，提供了一种高击穿的多铁性陶瓷基体。
摘要（英）：

The invention discloses a high-breakdown multiferroic ceramic. The stoichiometric formula of the high-breakdown multiferroic ceramic is (1-x) BiFeO3-xLaAlO3. The invention also discloses a preparationmethod of the ceramic material. The preparation method comprises the following steps: adding LaAlO3 into BiFeO3, and carrying out ball milling, drying, briquetting, sieving, cold isostatic pressing and sintering to obtain a (1-x) BiFeO3-xLaAlO3 ceramic sample. The high-breakdown (1-x) BiFeO3-xLaAlO3 ceramic material provided by the invention is simple in preparation process and low in material cost, and is environment-friendly, and a high-breakdown multiferroic ceramic matrix is provided.
