چکیده انگلیسی
We fabricated xBaTiO3 (BT)/(1-x)[BaTiO3-Bi(Mg1/2Ti1/2)O3-BiFeO3] (BT-BMT-BF)â¯+â¯0.1â¯wt%MnCO3 composites by spark plasma sintering and investigated the effect of BT content x, BT powder size, and BT-BMT-BF composition on piezoelectric properties. For xBT/(1-x)(0.3BT-0.1BMT-0.6BF) +â¯0.1â¯wt%MnCO3 (xâ¯=â¯0-0.75) composites with a 0.5-µm BT powder, the dielectric constant was increased with x, and the relative density was decreased at xâ¯=â¯0.67 and 0.75, creating optimum BT content of xâ¯=â¯0.50 with a piezoelectric constant d33 of 107â¯pC/N. When a larger 1.5-µm BT powder was utilized for the composite with xâ¯=â¯0.50, the d33 value increased to 150â¯pC/N due to the grain size effect of the BT grains. To compensate for a compositional change from the optimum 0.3BT-0.1BMT-0.6BF due to partial diffusion between the BT and 0.3BT-0.1BMT-0.6BF grains, a 0.5BT/0.5(0.275BT-0.1BMT-0.625BF)â¯+â¯0.1â¯wt%MnCO3 composite with the 1.5-µm BT powder was fabricated. We obtained an increased d33 value of 166â¯pC/N. These results provided a useful composite design to enhance the piezoelectric properties.
