A reflective particulate material comprises a particulate substrate, and a coating on the particulate substrate. The coated reflective particulate material may have a relative error of an amount of the coating on the particulate substrate of about 5% to about 15%, and/or a dust index of about 5 or lower, and/or a staining loss of about 8% to about 11%. A method of manufacturing the reflective particulate material comprises mixing the particulate substrate with a liquid coating composition to form a wet particulate mixture, passing the wet particulate mixture through at least one heat zone to remove water and/or moisture, and curing the coating material in the coating composition.

A method for manufacturing granulated silica. The method includes granulating silica powders each having a primary particle size of 5 to 50 nm by use of water, and hydrophobizing each surface of the silica powders with a silicon atom-containing hydrophobizing agent before or simultaneously with the granulation step.
