Popis:	In this work, Li2CO3 was added into 0.7[Formula: see text]0.3[Formula: see text][Formula: see text][Formula: see text]0.01molMnO2 (70BFBTMn) piezoelectric ceramics to reduce their sintering temperatures. 70BFBTMn ceramics were sintered by a conventional solid reaction method, and their structural, dielectric, piezoelectric and ferroelectric properties were studied. These results indicate that 0.5% (mole) Li2CO3 is the optimized content and it can reduce the sintering temperature by 100[Formula: see text]C, making the possibility of the piezoelectric ceramics cofiring with Ag electrodes at low temperatures to manufacture multilayer piezoelectric actuators.
