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.
Its high silicon dioxide content, typically around 95%, ensures that it is chemically inert, making it more resilient than regular sand. Furthermore, silica sand's high melting point and low thermal expansion coefficient make it an ideal material for various industries, from glassmaking to construction
The silica minerals when pure are colourless and transparent and have a vitreous lustre. They are nonconductors of electricity and are diamagnetic. All are hard and strong and fail by brittle fracture under an imposed stress. Some important physical properties of the silica minerals are compared in the Table.
Silica sand can range from nearly transparent to a darker gray. It is an odorless powder that can cause irritation to the skin or eyes on contact. Inhaling silica sand will also irritate the respiratory tract
One of the most common uses of silica sand is in water filtration, whether processing well water or filtering your tap water. Because of its uniform shape and size, silica sand is an effective filtration bed that consistently removes contaminants from water. Also, it does not degrade when exposed to acidic chemicals.
