Magnesium silicate (ion-exchange form)

Magnesium silicate is an inorganic mineral composed of magnesium, silicon, and oxygen (chemical formula varies, but common forms are MgO·SiO₂ and related structures)[4][6]. It can exist in a variety of crystalline and amorphous forms, including lamellar nanosheets and zeolite-like frameworks, which enable efficient ion exchange and adsorption[2][3]. Magnesium silicate is used in environmental and industrial applications for water purification, heavy metal immobilization (especially uranium[3]), and removal of silicic acid (silicate ions) and other anions via ion-exchange resins, particularly under alkaline conditions[1][5]. While not a molecular target for drugs or a component of biological signaling, it plays an important role in non-biological (industrial, environmental) remediation processes. Its ion-exchange capacity depends on its composition, structural features, and operational conditions such as pH and competing ions[2][3][5]. Magnesium silicate is not considered a therapeutic or diagnostic molecular target.
