General structure. A silicate mineral is generally an ionic compound whose anions consist predominantly of silicon and oxygen atoms.. In most minerals in the Earth39s crust, each silicon atom is the center of an ideal tetrahedron, whose corners are four oxygen atoms covalently bound to it. Two adjacent tetrahedra may share a vertex, meaning that the oxygen atom is a bridge connecting the two

Double Chain Ballandstick model of silicate double chains. Red balls correspond to oxygen, and gray to silicon atoms. Asbestos Asbestos from Greek , unquenchable is a group of fibrous silicate minerals containing double chains.
The essential characteristic of the amphibole structure is a double chain of cornerlinked siliconoxygen tetrahedrons that extend indefinitely parallel to the c crystallographic axis, the direction of elongation Figure 2. The tetrahedrons alternately share two and three oxygen atoms to produce a silicontooxygen ratio of 411.
A siliconoxygen tetrahedron is the SiO4 anionic group, or a silicon atom with four surrounding oxygen atoms arranged to define the corners of a tetrahedron. This is a fundamental component of most silicates in the Earths crust. A variety of silicate minerals can be identified by the way that the tetrahedra links differ, also by the cations

d Double chain silicates. 33 Muscovite breaks easily into very thin layers. The reason is 1 It is an ortho silicate containing discrete units of SiO 4 2tetrahedra. 2 It is a framework silicate. 3 It is a phyllo silicate with layers which are held together by strong van der Waal39s forces.
Inosilicates Double Chain Silicates If such a substitution takes place, it creates a charge imbalance that must be made up elsewhere in the silicate structure. The other common elements in the Earth39s crust that enter the silicates do so in other types of coordination. Ions like Al 3, Mg 2, Fe 2, Fe 3
Silicate Structure Example Double Chain amphibole group of silicates The mineral kupfferite is a double chain silicate and has the formula Mg 7 Si 8 O 22 OH 2. The repeating unit in kupfferite is the Si 4 O 11 6ion, however, in order to avoid fractions for the magnesium cations in the formula the silicate anion formula is doubled to Si 8
The resulting structure is long and thin, as can be seen in this top view of a model of a doublechain silicate The doublechain is electrically charged and so must bond with a set of cations to become electrically neutral. The ideal formula for a doublechain of silica tetrahedra is Si 4 O 116.
Silicate Chains. Silicate minerals containing chains are termed inosilicates. They consist of single chains SiO 3 2 n, in which the silicon to oxygen atom ratio is 13, and double chains Si 4 O 11 6 n, in which the silicon to oxygen atom ratio is 411.
