Recently mobile communication fields need piezoelectric ceramic resonators and filters as possible as small. The length-extensional vibration mode of a rectangular piezoelectric ceramic plate has the advantage of the small size. but the mode has not been studied sufficiently because it was not used extensively until now. In this paper. PZT + x[wt%] Cr₂O₃ ceramics with rhombohedral phase were fabricated. And temperature stability for the mode of the ceramic specimen was investigated. Contrary to our expectations. addition of the stabilizer. Cr₂O₃did not promote the temperature stability for the mode in the PZT ceramic specimen with rhombohedral phase.
