A silicate is a compound containing an anionic silicon compound. The great majority of the silicates are oxides, but hexafluorosilicate ([SiF6]2â) and other anions are also included. 4 or its compounds. Related to orthosilicate are families of anions (and their compounds) with the formula [SiO2+n]2nâ.
Faujasite silica is another form of crystalline silica. It is obtained by dealumination of a low-sodium, ultra-stable Y zeolite with a combined acid and thermal treatment. The resulting product contains over 99% silica, has high crystallinity and high surface area (over 800 m 2 /g).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.
