Abstract [en]

Temperature-dependent in-situ Raman spectroscopy is used to investigate the phase transformation of zinc metastannate (ZnSnO<inf>3</inf>) to zinc orthostannate (Zn<inf>2</inf>SnO<inf>4</inf>) induced upon annealing in the ambient. ZnSnO<inf>3</inf> microcubes (MCs) were synthesized at room temperature using a simple aqueous synthesis process, followed by characterization using electron microscopy, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetric analysis (TGA). Annealing of the ZnSnO<inf>3</inf> MCs was carried out up to 1000°C, while recording the Raman spectra in-situ at regular intervals. Phase transformation from metastannate to orthostannate was found to begin around 500°C with an activation energy of ~0.965 eV followed by the recrystallization into the inverse spinel orthostannate phase at ~750°C. Results from this study provide detailed understanding of the phase transformation behavior of perovskite ZnSnO<inf>3</inf> to inverse spinel Zn<inf>2</inf>SnO<inf>4</inf> upon thermal annealing.
