In chemistry, a silicate is any member of a family of anions consisting of silicon and oxygen, usually with the general formula [SiO₄₋ₓ]ₙ, where 0 ≤ x < 2. The family includes orthosilicate SiO⁴⁻₄ (x = 0), metasilicate SiO²⁻₃ (x = 1), and pyrosilicate Si₂O⁶⁻₇ (x = 0.5, n = 2). The name is also used for any salt of such anions, such as sodium metasilicate; or any ester containing the corresponding chemical group, such as tetramethyl orthosilicate.
