SilikatenNetzen
SilikatenNetzen are extended three-dimensional frameworks formed by silicate tetrahedra that share oxygen atoms. Each silicon atom is coordinated to four oxygen atoms, and neighboring tetrahedra connect at their corners to build a continuous Si–O–Si network. The degree of polymerization of the network, often described by the distribution of bridging and non-bridging oxygens, strongly influences the material’s properties.
In the structural taxonomy of silicates, network-forming frameworks are exemplified by tectosilicates, which include quartz and
SilikatenNetzen also encompass related network structures found in synthetic materials, including glassy silicates and geopolymers, where
Natural occurrence and industrial relevance are broad. Silicate networks make up the bulk of the Earth’s crust
