Materials for piezoceramics

Piezoceramic materials are used in devices converting mechanical actions to electrical signals (direct piezoeffect), electrical signals to mechanical forces (inverse piezoeffect), or electrical signals into electrical signals (successive use of direct and inverse effects). Piezoelectric materials are ferroelectric compositions or their solid solutions which are made by the synthesis of a mixture of different oxides, carbonates and salts of metals.

The bases of the most present piezoelectric materials are solid solutions of lead zirconate-titanate (LZT) modified by different additives.
