Abstract  

Bi-peroxotitanate was synthesized by a peroxo method and after thermal decomposition Bi2Ti2O7 was obtained. DTA, TG and DSC curves of Bi2[Ti2(O2)4(OH)6]5H2O were recorded and used to determine isothermal conditions suitable for obtaining the intermediate samples corresponding to the phases observed during the thermal decomposition. The samples were identified by quantitative analysis, IR spectroscopy and X-ray analysis. The experimental results were used to propose a mechanism of thermal decomposition of the investigated compound to a nanosized Bi2Ti2O7. The optimum conditions were also determined for obtaining Bi2Ti2O7, which is applicable for piezosensors.
