Silica sand is a term normally applied to high purity silica sand products with closely controlled sizing. Silica is the name given to a group of minerals composed solely of silicon and oxygen, the two most abundant elements in the earth’s crust. In spite of its simple chemical formula, SiO2, silica exists in many different shapes and crystalline structures. Found most commonly in the crystalline state, it also occurs in an amorphous form resulting from weathering or plankton fossilization. Silica sand is pumped down holes in deep well applications to prop open rock fissures and increase the flow rate of natural gas or oil. In this special application, round, whole grain deposits are used to maximize permeability and prevent formation cuttings from entering the well bore. Silica’s hardness and its overall structural integrity combine to deliver the required crush resistance of the high pressures present in wells. Its chemical purity is required to resist chemical attack in corrosive environments.
