The effect that the permittivity of antiferroelectrics depends on the elastic stress has been discussed with special interest to the load sensor applications. Although sodium niobate (NaNbO$_3$) employed in
this work as a typical antiferroelectrics has been hitherto known very difficult to obtain as a densely sintered ceramic body, we have successfully obtained the dense ceramics by investigating their nonstoichiometric compositions. Their electrostatic capacitance was determined from the output frequency of the timer oscillator circuit. In case of the ferroelectrics, their permittivity depends not only on the elastic stress but also on the elapsed time after a fixed stress application, whereas such unsteady behavior was not observed in the antiferroelectric sodium niobate. The phenomenon has been discussed from the view point of the interaction between the polarization and space charges, which exist only in ferroelectrics but in antiferroelectric. |
