They are very delicate. Lead zirconate titanate PbZr0 3-PbTi0 3 (abbreviated to PZT) which is the primary component of the piezoelectric material is used as an example for explanation. Well below resonance the material acts as a capacitor, and the product of the dielectric constant, the voltage constant and the vacuum permittivity gives the charge constant. The crystal structure of a material changes at the Curie temperature from piezoelectric (non-symmetrical) to a non-piezoelectric (symmetrical) form, and the material loses its piezoelectric properties. In summary, for high Q factor resonators quartz-like materials, for transducers PZT-like materials are recommended. They exhibit properties not usually present in other types of piezoelectric ceramics. As PZT’s have an increased electromechanical coupling coefficient, these can be implemented for the conversion of mechanical pressure to electric energy. Moreover, Rochelle salts are easily affected by voltage. PZT materials that are ferroelectrically hard can be subjected to very high mechanical and electrical stresses without affecting noticeable changes to their properties. On the other hand, natural crystalline structures, such as quartz (silicon dioxide, SiO2) exhibit large Q factor, and therefore well suited for resonators or frequency stabilizers in watches.
