  • What Is the Chemical Composition of Sand? - Reference

    2020-4-2  The chemical composition of sand is primarily SiO2, or silica. Silica, which is also named as quartz, is a type of mineral that makes up most of the sand types like beach sand. Quartz, which does not break easily, can be found in various types of rocks. Granite, which is a plutonic rock, and sandstone, which is a sediment rock, both have a high ...
