Abstract(in English) | Sol-gel composites have been developed for high temperature ultrasonic transducer application because of. their thermal durability. Sol-gel composite is composed of powder phase, sol-gel phase, and air phase and piezoelectricity is mainly derived from powder phase. For traditional piezoelectric sol-gel composite, PZT sol-gel solution had been used because of high dielectric constant, however, lead-free material is preferred, dielectric constant of PZT drops drastically above Curie temperature and it results in electrical impedance mismatch at high temperatures, and it can be failure reason during poling process. In this study, non-piezoelectric material was used as sol-gel phase and property difference was demonstrated empirically. |
