A solid-state route was used to prepare sodium titanium oxide (NTO, Na2Ti3O7) as a solar heat protecting material with animpressive solar reflectance (TSR = 94.3%) using a high refractive index rutile TiO2. The solar reflectance of the synthesizedNTO was measured using UV-Vis-NIR spectrophotometer. Solar reflectance property of the synthesized compound dependson the calcination temperature. The solar reflectance property of the synthesized NTO powder was compared with commercialrutile TiO2. The compound synthesized at 900 oC for 24 hrs had remarkable solar reflectance 94.3% than that calcined below900 °C. Crystalline nature, structural property, morphology and optical properties of NTO powders were characterized andanalyzed using XRD, FE-SEM, EDS and UV-Vis-NIR spectrophotometer. From the results, we guessed that NTO would bea suitable “solar heat protecting candidate” for energy-saving applications in coating industries.
