What is the melting point of silica sand?
What temperature causes melting of the free silica? In pure, natural form, SiO2 crystals are minute, very hard, translucent, and colorless. The physical properties are: molecular weight, 60.09; melting point, 1710 C; boiling point, 2230 C; and vapor pressure, 10 mm Hg at 1732 C. Most mined minerals contain some Si02.
