What is Silica Sand? - Select Sands Corp
Chemically inert, silica will not degrade or react when it comes in contact with acids, contaminants, volatile organics, or solvents. Silica gravel is used as packing material in deep-water wells to increase yield from the aquifer by expanding the permeable zone around the well screen and preventing the infiltration of fine particles from the formation.
