Abstract
Reserchers at Penn State University undertook PZT-PSM based high power material development, loss mechanism analysis and high power origin investigation. Under high leve drive conditions, vibrational velocity (vo) increased relative to that of the base PZT-PSM ceramic. Most RE transition-metal substituents resulted in combinative hardening and softening doping effects in PZT-PSM ceramics, regardless of the ionic radii. Comparison of internal dipolar field and positive DC bias showed that they are the same as both stabilize preferred domain structures, lowering the loss factors.
