Abstract :
The size effect of BaTiO3 (BTO) is the most important issue to design the high-capacitance MLCCs in the next generation. In the size effect of BTO ceramics and powders, the maxima of the permittivity were observed at certain grain size and the particle size. The permittivity maximum in the ceramics was due to the domain wall contribution, while that in the powders related with the complex structure of the BTO powders. Computer simulation technique was developed to predict the limit of capacitance density of the multilayer ceramics capacitors (MLCCs) produced by the current technology.
