Silicon dioxide, also known as silica (from the Latin silex), is a chemical compound that is an oxide of silicon with the chemical formula Si O 2. It has been known since ancient times.Silica is most commonly found in nature as quartz, as well as in various living organisms.he solubility of silicon dioxide in water strongly depends on its crystalline form and is 3â4 times higher for silica than quartz; as a function of temperature, it peaks at about 340 Â°C.
Silicon dioxide. Silicon dioxide silica is the mineral quartz and is a giant molecule with a melting point of over 16000C. Methanol is a molecular compound (an alcohol) with aâ¦ melting point of -980C.
