| Abstract: | Bi-peroxotitanate
was synthesized by a peroxo method and after thermal decomposition Bi2Ti2O7
was obtained. DTA, TG and DSC curves of Bi2Ti2(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. |
