silicon dioxide (sĭl'ĭ-kə) A chemical compound that is the main constituent of most of the Earth's rocks. Silica occurs naturally in five crystalline forms (quartz, tridymite, cristobalite, coesite, and stishovite), in a cryptocrystalline form (chalcedony), and in an amorphous form (opal). It is also the main chemical compound in sand. Silica is used to make glass, concrete, and other materials. Also called silicon dioxide.

- 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.lant materials with high silica phytolith content appear to be of importance to grazing animals, from chewing insects to ungulates. Studies have shown that it accelerates tooth wear, and high levels of silica in plants frequently eaten by herbivores may have developed as a defense mechanism against predation.

Silica - Silicon Dioxide (SiO2) Silica is used as a raw material feedstock for the production of glass where it is mixed with lime and soda to produce domestic glass for windows, bottles, jars, light bulbs and plate glass. Alternatively it may be mixed with boron oxide and soda to produce thermal shock resistant glass for cooking such as Pyrex.
