ABSTRACT |
After manufacturing 2mol% CdO substitute $0.05Pb(Mn_{1/3}Sb_{2/3})O_3-0.95Pb(Zr_{0.52}Ti_{0.48})O_3$ piezoelectric ceramics powder as starting material, to manufacture green sheets using Doctor Blade method. The optimum composition of slurry was studied. Moreover, the sintering properties and the dielectric and piezoelectric properties with variation a thickness of the manufactured sheets were investigated. The optimum of slurry was investigated by the rheology with addition of additives, the sintering condition was decided by TGA. And the properties of sheet were investigated through SEM. XRD. The optimum of slurry was the stablest at dispersant 3.0 wt% to solid loading 30vol%. After, at addition of binder/plasticizer(0.75/0.25) 3.0wt%, viscosity was 7.55Pa${cdot}$s. The dielectric and piezoelectric properties of the sheet were increased a little with the increasing of sintering temperature but were not variable with variation of sheet thickness. |
