Silicon dioxide – Wikipedia
Silicon dioxide reacts with elemental silicon at high temperatures to produce SiO: SiO 2 + Si → 2 SiO Water solubility. The solubility of silicon dioxide in water strongly depends on its crystalline form and is three-four times higher for silica than quartz; as a function of temperature, it peaks around 340 °C.
