Abstract

The infiltration behaviour of a tin melt, as an internal electrode, to the porous layers, and the electrical properties of multilayer ceramic capacitors was investigated by electrode infiltration. By preventing green-state delamination between the dielectric green sheet and the carbon paste, uniform porous layers, 5 μm thick, could be formed after sintering. When 15 vol % ceramic pillars were added to the carbon paste, the porous layer of the sintered samples could be considered as a porous solid formed by many pores larger than 4 μm. The critical pressure for the infiltration of tin melt into such a porous layer was found to be 0.5 MPa. With a high infiltration pressure, the resistivity of multilayer capacitors was decreased to 108–109Ωcm due to the growth of micro-defects formed on the surface of the dielectric layers during the lamination process.
