- Abstract
- 0.06Pb(Mn⅓Nb⅔)O₃-xPbZrO₃-(0.94-x)PbTiO₃ ceramics with x value near MPB(Morphotropic Phase Boundary) were fabricated and their piezoelectric properties and temperature coefficients of resonance frequency were measured. As ceramic phase change from tetragonal to rhombohedral through MPB, temperature coefficient change from positive value to negative one. MPB is estimated to be between Zr/Ti=48/46 and 51/43. Ceramics whose phase are in MPB have larger electromechanial coupling factor and dielectric constant than the others.
