Composite Dielectrics BaTiO3–Fe Consolidated via Field‐Assisted Sintering Technology

IET Nanodielectrics, Volume 8, Issue 1, January/December 2025.
The composite barruim titanate–iron was consolidated via field‐assisted sintering (FAST). The dielectric properties were evaluated. The material behaves well in a wide range of frequencies and temparatures. ABSTRACT The composite cermet material based on BaTiO3 ceramics doped with Fe was compacted using the field‐assisted sintering technology (FAST ...

Stability of giant dielectric properties in co‐doped rutile TiO2 ceramics under temperature and humidity

IET Nanodielectrics, Volume 7, Issue 4, Page 273-281, December 2024.
Dense ceramic microstructure of TiO2 co‐doped with Ta2O5 and Indium Tin Oxide can be fabricated using a low sintering temperature. Low loss tangent and high dielectric permittivity with excellent temperature–humidity stability are achieved in TiO2 co‐doped with Ta2O5 and Indium Tin Oxide. Abstract This research investigated the influence of temperature

Breaking the loss barrier in CCTO: sol–gel tin enables high permittivity with capacitor-grade loss tangent

Results in Physics
Sn-doped CaCu3Ti4O12 (CCTO) ceramics were synthesized by a sol–gel polymerization route using tin (II) acetate and low-temperature sintering (1015–1020 °C) to overcome the long-standing trade-off between colossal permittivity and dielectric loss (tan δ).
