Silica
Silica, also known as silicon dioxide (SiO 2) or mineral quartz, is a derivative compound of the chemical element silicon (Si) and makes up approximately 59% of the Earth's crust and a large part of common sand. Silicon links up with oxygen to form silicates, which are the most common suite of minerals.
