Abstract
A self-consistent method based on the interaction of a piezoelectric sphere with a piezoelectric medium that has anisotropic elastic and dielectric pr operties is used to calculate the components of the tensor piezoelectric mo dulus of BaTiO3 ceramic in all three ferroelectric modifications. A compari son of the calculated and measured piezoelectric moduli shows that at least 60-70% of the piezoelectric effect in BaTiO3 ceramic is caused by domain b oundary movement throughout the entire ferroelectric region.
