Abstract
- The supercapacitor based piezoelectric material composite (Na,K)NbO 3 –CaCu 3 Ti 4 O 12 (NKN–CCTO) is investigated for possible application in piezoelectric devices. (1− x )NKN– x CCTO (0.015≤ x ≤0.06) with different sintering conditions is researched for supercapacitor based piezoelectric applications. The 0.94NKN–0.06CCTO composite sintered at 975 °C shows the highest dielectric permittivity of 796. Clear SEM images of (1− x )NKN– x CCTO reveal that these compositions have high density well-crystallized structures. The composition and sintering temperature dependence of dielectric permittivities and piezoelectric coefficients, plotted in three dimensions, show that the 0.985NKN–0.015CCTO composite sintered at 1025 °C has a moderate dielectric permittivity of 405 and a piezoelectric constant of 98 pC/N.
