      abstract     = {BaTiO3-Ni nanopowders have been synthesized via an
                      alkoxide-mediated synthesis route through the hydrolysis and
                      condensation of barium hydroxide octahydrate and titanium
                      (IV) isopropoxide in the presence of submicron sized,
                      spherical Ni particles originating from a commercial Ni
                      paste, that was introduced during the preparation procedure.
                      X-ray diffraction (XRD) patterns indicate that nanocomposite
                      powders of the phases BaTiO3 and Ni could be successfully
                      prepared and tailor-made composition control was confirmed.
                      Scanning electron microscopy (SEM) and transmission electron
                      microscopy (TEM) show that the synthesized BaTiO3
                      nanoparticles were aggregates of nanosized primary particles
                      as small as 40 nm in diameter. The average Ni particle size
                      was estimated to be about 200 turn. Dilatometric
                      measurements on green compacts of these powders revealed
                      that the shrinkage of BaTiO3-Ni composites is retarded
                      compared to both, pure BaTiO3 and Ni. Thermogravimetric
                      analysis (TGA) shows weight losses due to the decomposition
                      of organic binder from Ni paste, the release of water from
                      the surface and of hydroxyl ions from inside the lattice of
                      the BaTiO3 nanoparticles. With the addition of nickel, the
                      dielectric constant increased slightly due to the
                      percolation effect. (C) 2009 Elsevier Ltd. All rights
