Grain-size effects on thermal properties of BaTiO3 ceramics

Dense nanocrystalline BaTiO 3 ceramics are successfully prepared by the high pressure assisted sintering. Microstructures are observed by scanning electronic microscopes. The grain sizes are estimated to be about 30 and 150 nm. In comparison, BaTiO 3 ceramics with the grain size of 600 nm and 1.5 μm...
