Abstract

Theoretical equations for remanent polarization and coercive force of ferroelectric ceramics with closed pores are derived as a function of shape factor and volume fraction of closed pores, based on the modified cubes model. This theory is applied to the experimental results obtained by Nagata with good agreement between theoretical and experimental ones.
