What Is Silica Sand How Is It Different From Regular Sand?

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. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ideal for use as filtration media and abrasive ...
