Bi0.5Na0.4Li0.1MxTi1-xO3 unleaded antiferroelectric high energy density ceramic and preparation method thereof

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

The invention relates to a Bi0.5Na0.4Li0.1MxTi1-xO3 unleaded antiferroelectric high energy density ceramic and a preparation method thereof. X satisfies the relation of 0.03<= x<=0.3; M is one of (Me1/3Nb2/3), (Mb1/2Nb1/2), (Me1/3Ta2/3) and (Mb1/2Ta1/2); Me in (Me1/3Nb2/3), (Mb1/2Nb1/2), (Me1/3Ta2/3) and (Mb1/2Ta1/2) represents one of Mg, Zn and Ni; and Mb in (Me1/3Nb2/3), (Mb1/2Nb1/2), (Me1/3Ta2/3) and (Mb1/2Ta1/2) represents one of Al, Co and Cr. The method employs a high temperature and pressure sintering furnace for preparing the Bi0.5Na0.4Li0.1MxTi1-xO3 unleaded antiferroelectric high energy density ceramic, which has energy density calculated based on the ferroelectric hysteresis loop up to 0.8-1.6 J / cm<3>.
