DTA and DSC curves of Cd2[Ti2(O2)2O(OH)6]·H2O were recorded and used to determine the
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 CdTiO3. The optimum
conditions were also determined for obtaining CdTiO3
with well-defined crystallinity.
