Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz a chemically inert and relatively hard mineral.What are the properties of silica sand.Silica sand constitutes of high performance properties such as brightness, reflectance, oil absorption and colour consistency. These properties help to improve the overall appearance and durability of industrial and architectural paints and coatings.
