Piezoelectric sensitivity and electromechanical coupling in a novel corundum-containing 3-0-type composite

A novel 3-0-type composite, that contains ferroelectric (PZT-type) and corundum ceramics, is studied to show features of the piezoelectric response and anisotropy of electromechanical coupling factors. The corundum ceramic is applied as a component with a large elastic stiffness. Almost equal volume...

Description
Summary:A novel 3-0-type composite, that contains ferroelectric (PZT-type) and corundum ceramics, is studied to show features of the piezoelectric response and anisotropy of electromechanical coupling factors. The corundum ceramic is applied as a component with a large elastic stiffness. Almost equal volume fractions of corundum m c and air pores m p are detected at 0.05
