Microstructural and electrical properties of Na1/2Bi1/2TiO3-(Na1/4Bi3/4)(Mg1/4Ti3/4)O3 piezoelectric ceramics

► The Td went downward and the Tm had no significant change. ► NBMT addition could stabilize the antiferroelectric phase. ► The piezoelectric properties of the ceramics are sensitive to compositions. ► The composition with x = 0.06 exhibits highest piezoelectric properties.
