Abstract
Vanadium dioxide (VO₂) of monoclinic phase exhibits Metal Insulator Phase Transition (MIPT) phenomenon involving a sharp change in electrical and optical properties at 68oC. Solution-based process is applied to form uniform VO₂ coating layer on ceramic tiles. This can selectively block the near-infrared light to possibly reduce the energy loss and prevent dew condensation caused by the temperature difference. Heat treatment conditions including temperature and dwell time were examined to obtain a monoclinic VO₂ single phase. Both rutile and monoclinic VO₂ phases were observed from in the tiles post-annealed below 700℃. Desired monoclinic VO₂ single phase was grown in the tiles heat treated at 750℃. Nano facets of irregular size were observed in the monoclinic VO₂ phase involving the phase-transition. Grain growth of monoclinic VO₂ phase was observed as a function of dwell time at 750℃.
