Re2x/3(Ba0.06Bi0.47Na0.47)1-xMeyTi1-yO3 leadless antiferroelectric high-energy density ceramic and preparation method thereof

FENG QIN / YUAN CHANGLAI / ZHOU XINGXING / YANG TAO / ZHOU CHANGRONG / XU JIWEN / LI QINGNING / CHEN GUOHUA

The invention relates to Re2x/3(Ba0.06Bi0.47Na0.47)1-xMeyTi1-yO3 leadless antiferroelectric high-energy density ceramic and a preparation method thereof. x is greater than or equal to 0.02 and is less than or equal to 0.2, y is greater than or equal to 0 and is less than or equal to 0.1, Re represents one of La, Sm, Nd, Gd, Dy and Er and Me represents one of Zr and Sn. The preparation method comprises synthesizing Re2x/3(Ba0.06Bi0.47Na0.47)1-xMeyTi1-yO3 powder by a traditional powder synthesis technology, and preparing the Re2x/3(Ba0.06Bi0.47Na0.47)1-xMeyTi1-yO3 leadless antiferroelectric high-energy density ceramic by a spark plasma sintering (SPS) technology. The preparation method is simple and efficient and has energy density of 0.7-1.6J/cm<3> calculated based on a ferroelectric hysteresis loop.
