In chemistry, orthosilicate is the anion SiO 4, or any of its salts and esters. It is one of the silicate anions. It is occasionally called the silicon tetroxide anion or group. Orthosilicate salts, like sodium orthosilicate, are stable, and occur widely in nature as silicate minerals, being the defining feature of the nesosilicates. … See more The orthosilicate ion or group has tetrahedral shape, with one silicon atom surrounded by four oxygen atoms. In the anion, each oxygen carries a unit negative charge. The Si–O bond is 162 pm long.
