abstract = {BaTiO3 nanopowders prepared by two different wet chemical
routes, one based on microemulsion-mediated synthesis (M-BT)
and the other one on the alkoxide-hydroxide method (A-BT)
were consolidated by spark plasma sintering (SPS). The
densification process, the linear shrinkage rates and the
relative densities achieved were strongly dependant on the
synthetic route. The results show that fully densified
BaTiO3 ceramics with a grain size of about 200 nm can be
obtained in both cases by controlling the sintering
temperature during the SPS process. The study of dielectric
properties revealed that M-BT derived ceramics show higher
permittivity values compared to those obtained for A-BT. The
influence of the barium/titanium ratio on the sintering
behavior and the dielectric properties is discussed. (C)
