www.britannica.com/science/tectosilicateTectosilicate, any member of a group of compounds with structures that have silicate tetrahedrons (each a central silicon atom surrounded by four oxygen atoms at the corners of a tetrahedron) arranged in a three-dimensional lattice. Each of the oxygen atoms of a given tetrahedron is shared with another tetrahedron.
www.merriam-webster.com/dictionary/tectosilicateTectosilicate definition is - a polymeric silicate in which the silicon-oxygen tetrahedral groups are linked by sharing all of their oxygen atoms with other such groups so as to form a three-dimensional structure or network.
en.wikipedia.org/wiki/TectosilicateSilicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of the Earth's crust.. In mineralogy, silica (silicon dioxide) SiO 2 is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphs.. On Earth, a wide variety of silicate minerals ...
en.wiktionary.org/wiki/tectosilicatetectosilicate (plural tectosilicates) ( mineralogy ) Any of various silicate minerals , mostly aluminosilicates , with a three-dimensional framework of silicate tetrahedra with SiO 2 or a 1:2 ratio , making up the greater part of Earth 's crust .
www.sciencedirect.com/topics/earth-and-planetary-sciences/tectosilicateNatural zeolites are crystalline, tectosilicate minerals composed of silica and aluminum tetrahedra linked to each other through shared oxygen atoms. Because of the latter, zeolites have a ring-style, open, three-dimensional, infinite crystal structure consisting of interconnected cavities and channels (Fig. 23.1).
encyclopedia2.thefreedictionary.com/tectosilicateIn the tectosilicate structure of quartz, in which there is no center of symmetry, enantiomorphism results from how the tetrahedral Si[O.sub.4] polyhedra connect, at their points, to form helical chains, which, like spiral staircases, turn either clockwise or counterclockwise.

www.galleries.com/minerals/silicate/tectosil.htmThe Tectosilicate Subclass is often called the "Framework Silicates" because its structure is composed of interconnected tetrahedrons going outward in all directions, forming an intricate framework analogous to the framework of large building. In this subclass all of the oxygens are shared with other tetrahedrons giving a silicon to oxygen ratio of 1:2.
www.tulane.edu/~sanelson/eens211/tectosilictes&others.htmThe tectosilicates or framework silicates have a structure wherein all of the 4 oxygens of SiO 4-4 tetrahedra are shared with other tetrahedra. The ratios of Si to O is thus 1:2. Since the Si - O bonds are strong covalent bonds and since the structure is interlocking, the tectosilicate minerals tend to have a high hardness.
