Performance and Temperature Stability of Lead-Free SNBTS Dielectrics

Caption

(Left) Performance comparison between lead-free dielectrics previously reported in the literature and the materials developed in this study. The stars indicate the reference material without tin (SNBT) and the materials containing 1 and 2 mol% Sn (SNBTS1 and SNBTS2), respectively. Materials positioned farther toward the upper right exhibit both higher dielectric constants and better temperature stability. (Right) Comparison of the temperature-dependent dielectric constants of the materials developed in this study with those of barium titanate (BaTiO₃), a representative dielectric material. While the dielectric constant of barium titanate changes sharply at around 125°C, SNBTS1 and SNBTS2 maintain relatively stable dielectric constants over a broad temperature range.
