Abstract
A reflective particulate material includes a particulate substrate having high total solar reflectance, bulk and apparent densities and toughness, and a low dust index. The reflective particulate can have a total solar reflectance of 80% to 87%, a toughness of 1% or fewer fines, an apparent density of 2.75 g/cm3 or greater, and a dust index of 1 or lower. A method of manufacturing the reflective particulate material includes preparing a slurry of the particulate substrate, spray drying the slurry to form a spray dried particulate, crushing the spray dried particulate to form a crushed particulate, and heating/calcining the crushed particulate. The heated, crushed particulate may further be coated to form a coated roofing granule.
