| 摘 要： | A novel process termed low-temperature combustion-synthesis(LCS)of Ba(ON3)2-TiO2-C6H8O7.H2O system was investigated at the initial temperature of 600℃ and ultrafine BiTiO3 powders with a particle size of 200-350nm were prepared.It was found that the molar ratio of NO3^-/citric acid and the homogeneity of combustion have remarkable effect on the characterstice of the powder,The reaction mechanism of LCS BaTiO3 powders was proposed on the basis of thermodynamic analysis.

| Abstract: | A novel process termed low-temperature combustion-synthesis (LCS) of Ba(NO3)-TiO-C6H8O7H2O system was investigated at the initial temperature of 600℃ and ultrafine BaTiO3 powders with a particle size of 200?350nm were prepared. It was found that the molar ratio of NO/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. |
