fosfaattikehyksen

Fosfaattikehyksen, also known as a phosphate framework, refers to a class of inorganic crystalline materials built from interconnected phosphate polyhedra. These structures are characterized by their diverse and often complex three-dimensional arrangements of PO4 tetrahedra linked through shared oxygen atoms. The specific connectivity and arrangement of these tetrahedra, along with the presence of interstitial cations, dictate the overall structure and properties of the phosphate framework.

Phosphate frameworks can exhibit a wide range of structural motifs, including layers, chains, and three-dimensional networks. This structural diversity arises from the ability of the phosphate group to coordinate with various metal cations, leading to a vast array of possible compositions and architectures. Examples of such materials include phosphates containing alkali metals, alkaline earth metals, transition metals, and rare earth elements.

The properties of fosfaattikehyksen are highly dependent on their specific composition and structure. They often display good thermal stability and chemical inertness, making them suitable for various applications. Research into phosphate frameworks has explored their potential use in areas such as ion exchange, catalysis, solid-state lighting, and as host materials for radioactive waste immobilization. The tunable nature of their structures and properties makes them an active area of materials science research.
