Lead-free antiferroelectric ceramic with high transition field and preparation method of lead-free antiferroelectric ceramic
The invention discloses a lead-free antiferroelectric ceramic material with a high transition field. The chemical formula of the lead-free antiferroelectric ceramic material is (1-x) NaNbO3-xBi2/3HfO3. The invention further discloses a preparation method of the ceramic material, Bi2/3HfO3 is added into NaNbO3, and a (1-x) NaNbO3-xBi2/3HfO3 ceramic sample is obtained through ball milling, drying, briquetting, sieving, isostatic cool pressing and sintering. The (1-x) NaNbO3-xBi2/3HfO3 ceramic material provided by the invention is simple in preparation process, low in material cost and environment-friendly, and a novel lead-free antiferroelectric ceramic material is provided.
一种具有高转变场的无铅反铁电陶瓷材料，其化学式为(1‑x)NaNbO3‑xBi2/3HfO3。本发明还公布了该陶瓷材料的制备方法，将Bi2/3HfO3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‑xBi2/3HfO3陶瓷样品。本发明提供的(1‑x)NaNbO3‑xBi2/3HfO3陶瓷材料制备工艺简单，材料成本低，绿色环保，提供了一种新的无铅反铁电陶瓷材料。
