Silica Sand is granular material that contains quartz and minute amounts of coal, clay and other minerals. It is also known as quartz sand and industrial sand, and is largely used in several construction applications. The presence of silica sand on metal materials can be a source of crevice corrosion on those metals. Silica sand is mechanically and chemically purified quartz sand, from which various products are created through hydro classification or thermal treatment. Еще
