Microstructure and Electrical Features of Nano-grained BaTiO3 Ceramics

초록

We investigated the microstructure, crystal structure, and electrical features of nano-grained BaTiO3 ceramics, which were synthesized from surface-coated BaTiO3 nano-powders; these powders were coated with Mn. The phase transition and physical features of the BaTiO3 ceramics were investigaed as a function of the sintering temperature and the amount of coating materials. The relation of the dielectric features of the nano-grained BaTiO3 ceramics with the structural variation is discussed in terms of process parameters.
