Abstract
Complex inorganic green pigments having a high near-infrared (NIR) solar reflectance were synthesized. Chromium oxide (Cr2O3) was used as the host component with mixtures of TiO2, Al 2O3, and V2O5 as the guest components. TiO2, Al2O3, and V 2O5 were mixed into 39 different compositions. It was found that a sample, denoted by S9, with the composition of Cr2O 3, TiO2, Al2O3, and V 2O5 are 80, 4, 14, and 2 wt%, respectively, gives a maximum NIR solar reflectance of 82.8% compared with 69.6% of a commercially available cool pigment powder. The comparison study on the effectiveness of the synthesized pigment and a commercial pigment on ceramic glaze and sprayed on ceramic tile roofs show that the new powder has given a better result by keeping the tested room about 2ฐC cooler. It can be concluded that the new formulated green pigment is a highly thermal effective as an NIR reflective roof coating. ฉ 2010 The American Ceramic Society.
