Abstract

PURPOSE:To increase a constant of voltage output by producing piezoelectric ceramics in which pores are distributed uniformly as a result of the manufacturing procedure wherein powdered resin insoluble in binder used for granulation and for forming is mixed in powdered raw material for the piezoelectric ceramics. CONSTITUTION:Powdered raw material for the piezoeelectric ceramics composed of PbTi0.44Zr0.44(Mg1/3Nb2/3)0.12O3 which has undergone reaction by preliminary baking is pulverized in wet, adding a specified amount of polycarbonate powder which is insoluble in aqueous solution of polyvinyl alcohol as binder and using water as a medium. Next, aqueous solution of polyvinyl alcohol is added as binder into the raw material for granulation and pressure forming with pressure of 1ton/cm<2>. After this, sintering at 1,200-1,300 deg.C is followed. Then, the products are cut into desired sizes, and silver electrodes are brazed on the products. By such manufacturing procedure, pores can be distributed uniformly in the ceramics so that the produced ceramics are made to be apparently softer, and the constant of voltage output which affects strength of the output voltages can be increased.
