Silica Sand - an overview | ScienceDirect Topics
Sand (silica or silicon dioxide) melts at 1710 °C, and sodium carbonate melts at 851 °C. These ingredients along with lime, CaO, make up a common type of glass known as soda-lime glass because it contains soda, lime, and silicon dioxide (Na 2 CO 3, CaO, and SiO 2) with the composition being about 25%, 12.5%, and 62.5%, respectively.
Sand - Wikipedia
The most common constituent of sand, in inland continental settings and non-tropical coastal settings, is silica (silicon dioxide, or SiO 2), usually in the form of quartz, which, because of its stone inertness and considerable hardness, is the most common mineral resistant to weathering.
