Abstract

PURPOSE:To increase the specific inductive capacity and electromechanical coupling coefficient of a piezoelectric porcelain composition by employing a mixture of PbTiO3, PbZrO3, Pb(ZnNb)O3, Pb(SnNb)O3 and WO3 specified in composition as a piezoelectric porcelain composition. CONSTITUTION:A composition made of V(PbTiO3)+W(PbZrO3)+X[Pb(Zn1/ 3Nb2/3)]+Y[Pb(Sn1/3Nb2/3)O3]+Z(WO3) is used for a piezoelectric porcelain composition, where V-Z are so defined as to become 0.30<=V<=0.55, 0.20<=W<= 0.60, 0.01<=X<=0.20, 0.01<=Y<=0.20, 0.001<=Z<=0.10. In this manner, the stock material is selected, pulverized by ball mill, wet kneaded, temporarily calcined at 700-900 deg.C, again pulverized by ball mill, a binder is added thereto, granulated to form a predetermined shaped by the pressure of 1 ton/cm<2>, and sintered with 1,100-1,250 deg.C.
