Rex/3(Ba0.06Bi0.47Na0.47)1-xTi1-xRxO3 leadless antiferroelectric ceramic with high energy density and preparation method thereof

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

The invention relates to Rex/3(Ba0.06Bi0.47Na0.47)1-xTi1-xRxO3 leadless antiferroelectric ceramic with high energy density and a preparation method thereof. x is greater than or equal to 0.02 and is less than or equal to 0.2, Re is one of La, Sm, Nd, Gd, Dy, Er and Y and R is one of Nb and Ta. Rex/3(Ba0.06Bi0.47Na0.47)1-xTi1-xRxO3 powder is synthesized by a traditional powder synthesis technology and Rex/3(Ba0.06Bi0.47Na0.47)1-xTi1-xRxO3 leadless antiferroelectric ceramic is prepared by a spark plasma sintering (SPS) technology. Energy density of the Rex/3(Ba0.06Bi0.47Na0.47)1-xTi1-xRxO3 leadless antiferroelectric ceramic with high energy density is calculated based on ferroelectric hysteresis loop and is in a range of 0.5-1.5J/cm<3>.
