dc.description.abstract | The effect of additional amount and particle size of BaTiO3 additive on shrinkage behavior and inter-diffusion in Ni-based internal electrodes has been investigated, in order to reduce the large shrinkage mismatch between the internal electrode and the dielectric layer and to control the thermal and/or residual stresses in multilayer ceramic capacitors (MLCCs). Ni powder of 100-500 nm and two kinds of BaTiO3 powders of 100 and 200 nm were used as matrix and additive, respectively. The Ni and BaTiO 3 powders were mixed with volume ratios of 95:5, 90:10, 85:15, respectively, and then cold-isostatic pressed. The shrinkage of starting materials and each composite was measured in a range of 700-1300°C with 150°C interval in H2/Ar atmosphere, using ASTM standard method. Diffusion phenomena at interface of Ni/BaTiO3 composites with 85:15 and 90:10 volume ratios were investigated using SEM, EDX, and TEM. The particle size affects the shrinkage behavior in relatively low temperatures below 1000°C, showing a turning point at that temperature. The final shrinkage of composites is matched with that of bulk BaTiO3 of smaller particle size, independent of additional amount of BaTiO3 additive. A reaction layer of about 1000 nm wide is observed at the interface between the Ni and BaTiO3 powders in the composite of 85:15 volume ratio. The quantitative amount of elemental Ni diffused into the BaTiO3 is about 9.7 mass% in the composite of 90:10 volume ratio, without another phase seen in the Ni. | - |
