WebSilicate definition, any of the largest group of mineral compounds, as quartz, beryl, garnet, feldspar, mica, and various kinds of clay, consisting of SiO2 or SiO4 groupings and one or … Silicates are generally inert chemically. Hence they are common minerals. Their resiliency also recommends their use as building materials. When treated with calcium oxides and water, silicate minerals form Portland cement . Equilibria involving hydrolysis of silicate minerals are difficult to study. See more In chemistry, a silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula [SiO 4−x] n, where 0 ≤ x < 2. The family includes orthosilicate SiO4−4 (x = 0), metasilicate SiO2−3 … See more Although the tetrahedron is a common coordination geometry for silicon(IV) compounds, silicon may also occur with higher coordination … See more • Alkali-silica reaction • Carbon cycle • Carbonate-silicate cycle • Ocean acidification See more In all silicates, silicon atom occupies the center of an idealized tetrahedron whose corners are four oxygen atoms, connected to it by single covalent bonds according to the See more Silicates with alkali cations and small or chain-like anions, such as sodium ortho- and metasilicate, are fairly soluble in water.
