Abstract

The synthesis of nanosize barium titanate by the combustion of redox mixtures containing different Ba-precursors (nitrate, acetate or peroxide) $TiO(NO3)_2$ and fuel (carbohydrazide, glycine or citric acid) was studied. The formation and nanosize nature of barium titanate were confirmed by X ray diffraction and transmission electron microscopy. A high order of porosity was observed as indicated by scanning electron microscopy. The combustion reaction was different depending on the precursor, fuel and the amount of gases liberated. This appears to control the product characteristics and microstructure. The liberation of a large amount of gases results in the product with greater porosity
