Abstract

Diffusion of silver was studied in a ceramic based on lead zirconate-titanate, Pb0.95Sr0.05(Zr0.53Ti0.47)O3+1 wt%. Nb2O5 (PZT), by means of a radio-tracer method. Parameters of silver diffusion and silver content in PZT after continuous diffusion saturation of the ceramic by this impurity were determined in the temperature range 500–850 °C. Concentration-depth profiles and silver content in the ceramic were obtained as a result of metal diffusion from the electrode during ceramic silvering. Our results show that silver has a high diffusivity. No evaporation of silver during metallization (Tmax=750 °C) was found, but part of it (∼ 0.1 mg cm−2) penetrates into the ceramic from the electrode to a depth of more than 1000 μm, and the silver concentration varies from ∼2×1019 to ∼2×1018 at cm−3. The silver concentration does not exceed 0.2 at% at diffusion saturation of the ceramic during 100–120 h over the temperature range 650–850 °C.
