A Novel Process for Synthesis of Ultrafine BaTiO3 Powders

摘要: 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.
