Abstract: Abstract In3+ and Nb5+ co-doped TiO2 (INTO) ceramics were sintered at 1400 °C for 5 and 10 h. The room temperature dielectric permittivity of the as-fired INTO ceramics significantly decreased from e′≈ 7824 to 4669 (at 1 kHz)…

Abstract: Abstract In this study, an improved method was developed for the preparation of lead-free (Ba1−xCax)(Ti0.91Sn0.09)O3 (BCTS) (0.02 ≤ x ≤ 0.07) ceramics by combining the conventional solid-state reaction with a gel precursor mixing method. The effects of Ca content…

Abstract: Sintering has been the most conventional way of fabrication of ceramics. However, it has been observed that sintering can induce compositional inhomogeneity, formation of secondary phases, formation of defects, internal stresses etc. Even though post…
