Ceramics properties and behaviours
WebApr 5, 2016 · The doped ceramics exhibit constricted hysteresis loops, which is associated with the restoring force of Li + –Al 3+ ionic pairs as a result of the Coulomb force between Li + and Al 3+ ions. The results show that the piezoelectric properties and corresponding temperature stability of the doped ceramics were enhanced significantly. WebOct 17, 2024 · Firstly, it should be noted that at low KNN ( x = 0.01 and 0.03) concentrations, the dielectric properties of these ceramics decrease markedly with respect to pure BNT. Also, a small increase in dielectric permittivity values can be observed for x = 0.05 and 0.06 concentrations.
