Abstract
A reflective particulate composition includes a particulate mixture that includes a particulate substrate, a hardness enhancer and a pigment. The reflective particulate substrate has a hydrophobic coating on the particulate mixture. The composition may have a solar reflectance of 70% or greater. The pigment may include a clay, and the particulate substrate may include a feldspar. A method of making the composition may include mixing the particulate substrate, the hardness enhancer, and the pigment to form a particulate mixture, heat treating the particulate mixture, and coating the heat treated mixture with the hydrophobic coating.
