Aug 01, 2021 Bambang Surya Diwanta in the thesis Silica Sand Purification Using Sonication Process In Oxalic Acid Media (2015) stated that high-purity silica sand contains a maximum of 0.003 iron (Fe) and a minimum of 99 percent silica oxide. Also read Substances Contained in Tobacco. Silica sand or silicon oxide is the basic ingredient for glass making.
