From Sand to Silicon - Intel

2018-1-9  Sand – especially Quartz - has high percentages of Silicon in the form of Silicon dioxide (SiO 2) and is the base ingredient for semiconductor manufacturing. Melted Silicon – scale: wafer level (~300mm / 12 inch) Silicon is purified in multiple steps to finally reach semiconductor manufacturing quality which is called Electronic Grade Silicon.

Silicon (Si) and water - Lenntech

The present current causes silicon to flow from sediments to seawater. Antarctic weathering also releases silicon. Silicon is removed from waters naturally, through plankton fixation, sediment settling, or reactions of dissolved silicon with clay minerals (reverse weathering). Sand is the primary substance for commercially produced silicon.
