Abstract

A novel process termed low-temperature combustion-synthesis (LCS) of Ba(NO₃)₂-TiO₂-C₆H₈O₇.centre dot H₂O system was investigated at the initial temperature of 600℃ and ultrafine BaTiO₃ powders with a particle size of 200-350 nm were prepared. It was found that the molar ratio of NO₃^-/citric acid and the homogeneity of combustion have remarkable effect on the characteristics of the powder. The reaction mechanism of LCS BaTiO₃ powders was proposed on the basis of thermodynamic analysis.
- low-temperature combustion-synthesis;
- barium titanate
