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.
