摘要：

Silver and Ag-Pd alloy are cofired with BaTiO3-based dielectries during the manufacturing of capacitors. The diffusion of silver into BaTiO3 during sintering is very slow. However, the vapor pressure of silver is high at temperatures greater than the melting point of silver (960 degrees C). The effect of the evaporation of silver during the sintering with BaTiO3 at 1200 degrees, 1250 degrees, and 1290 degrees C is investigated in the present study. The silver vapor can transport through the pore channel of the dielectrics to a distance of a few hundred micrometers. The melting point of Ag-Pd alloy is higher than that of silver; therefore, the transportation of silver vapor from Ag-Pd alloy is hardly observed at temperatures >1200 degrees C.
