Nanocrystalline BaTiO{sub 3} from gas-condensation process

PDF Version Also Available for Download.

Description

Nanocrystalline BaTiO{sub 3} can be prepared by gas condensation, with an average particle size as small as 18 nm. The stoichiometry of nanocrystalline BaTiO{sub 3} particles can be controlled precisely and reproducibly. Nanocrystalline BaTiO{sub 3} powders, fabricated by a novel e-beam evaporation method, show good sintering behavior which can be sintered to a high density at a temperature as low as 1200 C and exhibit a relatively large dielectric constant than that of coarse-grained ceramics. A thermal analysis was also carried out to assert the lowest limit temperature for forming nanostructured BaTiO{sub 3} from Ba/Ti oxidized clusters at ambient pressure.
