抄録

The diffusion of silver, Ag, as the electrode material in (Bi_1/2K_1/2)TiO₃ (BKT) ceramic were studied by means of a secondary ion mass spectrometry (SIMS). Some analytical methods of SIMS were applied to obtain Ag diffusion coefficient in BKT ceramics. Depth profile of Ag showed a simple concentration gradient from the surface towards the deeper side in BKT ceramics. From these profiles, the diffusion coefficients of Ag were calculated and obtained by the analysis. The temperature dependence of Ag diffusion in BKT ceramics was described by 2.2 × 10⁶ cm²/s of pre-exponential factor and 296 kJ/mol of the activation energy in the temperature range of 700–900°C as diffusion treatments.
