Abstract

PURPOSE:To obtain a material capable of being forming in thin plate with 1/3 of Poisson's ratio and 300 or higher of mechanical quality factor by calcining special composition under limited conditions. CONSTITUTION:A composition having a range of 0.025<=x<=0.125, 0.375<=y<= 0.618 as represented by the following formula xPb(Mg1/3Nb2/3)O3+(1-x-y) PbTiO3+yPbZrO3 or a composition containing CoO of 0.4-2.0mol% or Cr2O3 of 0.2-1.0mol% added to the above is calcined under limited conditions in high oxygen atmosphere to obtain a piezoelectric porcelain material.
