| 摘要 |
The piezoelectromagnetic ceramics is prepared by (a) mixing ternary oxide group compounds, Pb(Co1/3Nb2/3)O3-PbTiO3-PbZrO3, with 3-10 wt% PbO as an additive and acetone as a dispersive solvent by planetary mill, (b) calcinting the dried slurry at 750-900 deg.C and pulverizing the calcined body, (c) molding it with 700 kg/cm2 pressure, (d) sintering the pressed body at 1150-1300 deg.C for 0-8 hrs.. The sintering atmosphere changes from oxygen below sintering temp. to nitrogen or air at sintering temp.
