Giant Permittivity of Barium Titanate Prepared by Ultra-Fast Sintering Method

Abstract:

Recently work shown that an imperfection interface can be deduced by a fast sintering, which termed as Self-propagating High-temperature Synthesis plus Quick Pressing (SHS/QP). In order to investigate the effect of imperfection interface on the transport properties of function ceramics, the SHS/QP was applied to fabricate permittivity BaTiO₃ in this article. It was found that this ultra-fast sintering method could not only lead to a broaden-amorphous grain boundary but also semi-conductive grain body simultaneously. It is interesting that the new rapid route can result in the giant permittivity of BaTiO₃.
