What is the classification of silicates?

What is the classification of silicates?

The three types of silicates are (i) Orthosilicates, (ii) Pyrosilicates, (iii) Cyclic silicates.

What are the 6 classes of silicates?


  • Ortho silicates (or Nesosilicates)
  • Pyro silicate (or Sorosilicates)
  • Cyclic silicates (or Ring silicates)
  • Chain silicates (or pyroxenes)
  • Double chain silicate (or amphiboles)
  • Sheet or phyllosilicates.
  • Three dimensional (or tecto) silicates.

What are the four classes of silicates?

Silicone materials classification and their characteristics, and applications

  • General purpose silicone rubber.
  • High hardness silicone rubber.
  • High transparency silicone.
  • Thermal conductive silicone.
  • High heat resistance silicone rubber.

What are the 5 subclasses of silicate minerals?

The Silicates are divided into the following subclasses, not by their chemistries, but by their structures:

  • Nesosilicates (single tetrahedrons)
  • Sorosilicates (double tetrahedrons)
  • Inosilicates (single and double chains)
  • Cyclosilicates (rings)
  • Phyllosilicates (sheets)
  • Tectosilicates (frameworks)

How are silicates classified give examples?

number of silicate units liked by sharing two or more oxygen atoms are called inosilicates. Example : They are further classified as chain silicates and double chain silicates. (v) Chain silicates (or pyroxenes) : These silicates contain [(SiO3)n]2n- ions formed by linking .

How is a mineral classified?

Minerals are classified on the basis of their chemical composition, which is expressed in their physical properties. This module, the second in a series on minerals, describes the physical properties that are commonly used to identify minerals. These include color, crystal form, hardness, density, luster, and cleavage.

What are 3 examples of silicates?

The vast majority of the minerals that make up the rocks of Earth’s crust are silicate minerals. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a great variety of clay minerals.

How are silicates classified give an example?

Example : Tale, Mica etc. (viii) Three dimensional silicates (or tecto silicates) : Silicates in which all the oxygen atoms of `[SiO_(4)]^(4-)` tetrahedra are shared with other tetrahedra to form three-dimensional network are called three dimensional or tecto silicates. Examples : Quartz.

What are silicates class 11?

Silicates are the compounds in which the anion present are either discrete SiO44- tetrahedra or a number of such units joined together through corners.

What are silicates in chemistry?

Silicates are salts containing anions of silicon (Si) and oxygen. There are many types of silicates, because the silicon-to-oxygen ratio can vary widely. In all silicates, however, silicon atoms are found at the centres of tetrahedrons with oxygen atoms at the corners.
