In a certain frequency range, the mg-doped CCTO films have higher dielectric constants and good thermal stability. More critically, the doping of Mg reduces the grain boundary conductivity, enhances the grain boundary insulation and finally leads to a low dielectric loss tangent. the doping of Mg...
For the case of ceramics with 5 mol% Fe, the dielectric constant was 66,650 at 1000 Hz at room temperature, 19 times higher than that of pure BaTiO3 ceramics, while the dielectric loss tangent was 0.13. Comparison with other giant-permittivity materials demonstrated the superior potential of ...
hBN ceramics exhibit high thermal conductivity (130–150 W m−1 K−1 parallel to the plane and 22–25 W m−1 K−1 in the perpendicular direction)5, a low dielectric constant (4.0–5.4) and a low dielectric loss tangent (3 × 10–4)1. However, the generally ...
Giant dielectric permittivity (ε′) with low loss tangent (tanδ) was reported in (In + Nb) co‐doped TiOceramics. Either of electron‐pinned defect‐dipole or internal barrier layer capacitor model was proposed to be the origin of this high dielectric performance. Here, we proposed an...
