Abstract: LiNbO₃ piezoelectric particles of high Curie point coated by SiO₂ via solgel method were used and then LiNbO₃(SiO₂)/ZL102composites were fabricated through pressure infiltration. Damping properties from 30 °C to 350 °C were measured by dynamic mechanical thermal analyzer (DMTA). The results reveal that the damping capacity of LiNbO₃(SiO₂)/ZL102 composite is three times the value of ZL102 alloy and two times as high as LiNbO₃/ZL102 composite at 30 °C. And with increasing temperature the damping capacities of three types of materials increase together and gradually become close. In the present paper, piezo-damping was achieved by using poled LiNbO₃ piezoelectric particles. Moreover, the piezodamping was enhanced by SiO₂ coatings, which changed the resistivity around LiNbO₃ particles.
