The Resource Base of Silica Glass Sand versus Glass ...

Silica sand is mostly composed of quartz grains with a size of 0.1–2.0 mm, which are characterized by having a high content of quartz (min. 95%, even up to 99.9% SiO 2) and a low amount of impurities (e.g., Fe 2 O 3 even down to 0.01%). Silica sand can be produced from both loosely consolidated sand and by crushing weakly cemented sandstones.
