- Abstract
- Barium titanate has been prepared by solid-state reaction of
nanocrystalline TiO2 (70 nm) with BaCO3 of different particle
size (650, 140, and 50 nm). The results give evidence of a strong
effect of the size of BaCO3 in the solid-state synthesis of barium
titanate. The use of nanocrystalline BaCO3 already leads to
formation of the single-phase BaTiO3 after calcination for 8 h at
800°C. The final powder consists of primary particles of ~100
nm, has a narrow particle size distribution with d50=270 nm,
and no agglomerates larger than 800 nm. For the coarser carbonate,
4 h calcination at 1000°C are required and the final
powder is much coarser. Solid-state reaction of nanocrystalline
BaCO3 and TiO2 represents an alternative to chemical preparation
routes for the production of barium titanate ultrafine
powders. (literal)
