摘要
Nanosized tetragonal barium titanate has been directly prepared by low-temperature combustion synthesis process (LCS). According to thermochemical calculations of propellant chemistry theory, the optimum molar ratio of reactants was obtained with the Ba(NO3)(2)-TiO(NO3)(2)-citric acid-NH4NO3 system. The influence of the ratio of reactants on the properties of the final products was investigated. The results showed that tetragonal BaTiO3 with high purity was produced at low ignition temperature (similar to300 degreesC). The crystalline size of the powder obtained is less than. 50 nm. The crystal structure, crystalline size and morphology were analyzed by XRD, SEM and TEM. (C) 2003 Elsevier Science B.V. All rights reserved.
