Abstract

PURPOSE: To improve stability to applied voltage and deflective strength with the balance among kp-ε-Qm-tan δ kept good through the composition with Pb (Tiy Zrz)O3 and a piclore type composite oxide Sr2Sb2O7.
CONSTITUTION: Sr2Sb2O7 PBTIO3 and pbZrO3 made of oxides, carbonates, organic acid salts and the like of Pb, Ti, Zr, Sr and Sb as powdery raw materials are so blended as to compose a compound representing (1-x)Pb(TiyZrz)O3.x(Sr2Sb2 O7)1/2, provided that 0.2<y, z<0.8, y+z=1.0 and 0.001≤ x≤ 0.2. The compound thus composed is pressurized into a mold, sintered and polarized to form a piezoelectric porcelain. Here, one of the piclore elements, can be substituted by Cd, Pb or Ba. In addition, when this compound is provided with Mn of 0.01∼3.0% by weight of MnO2 equivalent thereto, Qm and tan δ are farther improved. This material is adapted for tremblers for high power ultrasonic wave generator or wide range ceramic filter
