In this current work, three methods

In this current work, three methods were used to prepare BaTiO3 powders, namely the hydrothermal reaction, atmospheric liquid-state method and hydrolysis method. The resulting BaTiO3 powders have significant differences in terms of morphology and particle size distribution. We have thus correlated particle crystallinity, size distribution and microstructure to the morphology-tuned sintering kinetics of the BaTiO3 ceramics, leading us to establish a structure property relationship between the structure of the nanopowder and the densification of ceramic. We believe that this relationship will provide a basis for an efficient fabrication of BaTiO3 transparent ferroelectric ceramics in the future.
