The sorption of Ca2+ on the surface of TiO2 nanoparticles in a saturated solution of Ca(OH)2 was observed by rapid heat evolution compared to the reference sample using isothermal calorimetric analysis. In addition to that, the interaction of TiO2 nanoparticles with a saturated Ca(OH)2 solution under hydrothermal conditions (40, 80, and 120°C) in an autoclave was carried out as well. Perovskite formed as a result of interaction between TiO2 and saturated Ca(OH)2 under temperatures of 80 and 120°C. Similarly, the formation of perovskite was found along with a hydration product when tricalcium silicate was hydrated in the presence of TiO2 nanotubes under hydrothermal condition (120°C). X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to investigate the presence of perovskite.
