inosilicate, any of a class of inorganic compounds that have structures characterized by silicate tetrahedrons (each of which consists of a central silicon atom surrounded by four oxygen atoms at the corners of a tetrahedron) arranged in chains.

Inosilicates are chain silicates which have interlocking chains of silicate tetrahedra with either SiO 3, 1:3 ratio, for single chains or Si 4 O 11, 4:11 ratio, for double chains. Wikimedia Commons …

The most important inosilicates are the pyroxenes. These have a general structural formula of: Z = Si +4 or Al +3 in tetrahedral coordination. Pigeonite is also a monoclinic pyroxene with a composition similar to the orthopyroxenes with more Ca substituting for Fe, and Mg.

The meaning of INOSILICATE is a class of polymeric silicates in which the silicon-oxygen tetrahedral groups share half of their oxygen atoms so as to form straight chains of indefinite length; also : a member of this class —called also metasilicate.

Minerals where the silicon-oxygen tetrahedra form chains are called inosilicates. They can take the form of single chains, where tetrahedra line up single-file through the sharing of oxygen atoms, or they can form double chains where the tetrahedra of adjacent single chains also …

Nesosilicates (meaning "island" silicates) are individual silicate anions arranged in crystalline ionic solids with their counterions. Those individual ions mean that nesosilicates are not network solids at all. They represent the extreme, other end of the silicate spectrum of structures. The nesosilicate anion forms a tetrahedral shape.

Inosilicates include two important groups of primary minerals: pyroxenes and amphiboles. You might find these chapters and articles relevant to this topic. J. Theo Kloprogge, Barry J. Wood, in Handbook of Mineral Spectroscopy, 2020.

2023年8月24日 · Inosilicates are also known as chain silicates because of the corner-sharing chains of silicate tetrahedra along z -direction. Apices of adjacent tetrahedra of each chain point to the opposite directions. Nature of these chains has …

Inosilicate refers to a subgroup of silicate minerals wherein silicon-oxygen tetrahedra are linked together in chains, providing a distinctive structural framework. These chains can be either single or double, aligning them voluminously in the classification of silicate minerals.

Cyclosilicate and inosilicate subclasses comprise numerous mineral groups and important mineral species. Cyclosilicates’ most familiar representatives are beryl and the tourmaline supergroup. Inosilicates are subdivided into single-chain silicates with pyroxene supergroup and double-chain amphibole minerals.
