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.

Silica Sand - an overview ScienceDirect Topics

2012-9-4  The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity, it has an extremely low specific surface area in the range from 40 to 160 cm 2 /g. The material usually contains more than 99.7% SiO 2, with absorbed water being at a negligible level (0.1%).
