Silicates are anionic compounds consisting of silicon and oxygen atoms. Most often, they occur in a combination of orthosilicates, metasilicates and pyrosilicates, depending on their configuration and organization. In the overall structure, silicon is surrounded by four oxygen atoms, forming tetrahedra.

Usually the common name is also used for any salt of silicon-oxygen anions, as well as any anions, having an Si atom, of a different structure. They constitute the largest group of minerals. Depending on the mixture, they can be used in construction as components of natural or synthetic materials.

An example of a silicate is tetraethoxysilane (TEOS) with the chemical formula Si(OC₂H₅)₄ – it is widely used in industry as a drying, cross-linking and insulating agent.
