Abstract
We studied sintering temperature to enhance the piezoelectric and ferroelectric properties of 0.98(Na0.5K0.5)NbO3-0.02Ba(Zr0.52Ti0.48)O3 lead free piezoelectric ceramics. The synthesis and sintering method were the conventional ceramic techniques, and sintering was executed at 1080–1120°C. We found that the NKN-BZT ceramics showed the highest piezoelectric properties and ferroelectric properties at an optimal sintering temperature. The NKN-BZT ceramics sintered at 1100°C showed superior performance, with piezoelectric constant d33= 213 ρC/N, and electromechanical coupling factor kp = 0.41%. These results reveal that NKN-BZT ceramics are promising candidate materials for lead-free piezoelectric applications.
