Effect of Sintering on the Piezoelectric Properties and Microstructure of Lead Free (Ba1-xCaxZr0.1Ti0.9O3) (x = 0.065) Ceramics
In this work, pellet samples of barium calcium zirconate titanate (Ba1-xCaxZr0.1Ti0.9O3, x=0.065) were prepared using solid state reaction route with double sintering. The structural and piezoelectric properties were measured. Further, SEM and EDAX analysis were observed. With different sintering temperature, the density and grain size of the prepared pellet samples were changed and further, their effect in piezoelectric properties has been observed. For the prepared samples, the converse piezoelectric constant (d33*) has been decreased with the increase in sintering temperature. The piezoelectric constant (d33*) was measured highest (153 pm/V) at 1300oC.
