Permittivity effects of particle agglomeration in ferroelectric ceramic-epoxy composites using finite element modeling Open
The size dependence of the dielectric constants of barium titanate or other ferroelectric particles can be explored by embedding particles into an epoxy matrix whose dielectric constant can be measured directly. However, to extract the par…

Barium titanate nanoparticles: Short-range lattice distortions with long-range cubic order Open
Barium titanate (BTO) nanoparticles (sizes 10 to 500 nm) exhibit a displacement of the Ti atom from the center of the Perovskite unit cell as inferred from synchrotron X-ray diffraction patterns (XRD) analyzed using atomic pair distributio…
