| Popis: | 98 The (Ba,Ca)(Ti,Zr)O3 was used as the primary dielectric material in this study. And the Mn-Si-O glass was applied in the BCTZ system as a sintering aids to prepare multilayer ceramic capacitor by BME process. The Yttrium/Silicon doped BaTiO3 material was applied as the constraining layer to inhibit the XY direction shrinkage and grain growth of BCTZ dielectrics while sintering. Then the constrained BCTZ will have smaller mean grain size after sintering process. The fast sintering technology was applied in this study also. It could reduce the internal stress caused by sintering shrinkage between base metal electrode and ceramic dielectric. The electrode continuity will become better and the capacitance will be increased. The experimental result shows that the constraining construction could inhibit the shrinkage and grain growth of BCTZ dielectrics indeed. The mean grain size could be inhibited around 0.6um after 1260 oC sintering process, the dielectric constant, dissipation factor and temperature dependence characters of capacitor will be affected. |
