Abstract

PURPOSE:To obtain a piezoelectric porcelain having a high performance and a mass productivity by combining x, y and z in KxNayLizNbO3 (x+y+z=1) within a certain range, and ading 0.05-0.5mol% of MnO as a by-product component. CONSTITUTION:After weighing and mixing powders of K2CO3, Na2CO3, Nb2O3, Li2CO3 and MnCO3 to a given amount those are sintered to form a solid solution of KNbO3-NaNbO3-LiNbO3. When this composition is shown by KxNayLizNbO3 (x+ y+z=1) defining a total value of x, y and z within the above range and further a certain amount of MnO is added therein as a subcomponent, the dielectric constant decreases more by keeping low the value of the mechanical quality constant as a vibrator, and a electric mechanical coupling factor increases in the diameter direction, thereby being able to obtain a piezoelectric porcelain having a low dispersion. Furthermore, the effect of MnO2 is low in case of less than 0.05mol%, while an uniform porcelain is not obtained in case of more than 0.5mol%.
