GeezerVison is showing en.wikipedia.org — Aluminosilicate - Wikipedia This article is about a class of minerals. For related neutral compounds composed solely of aluminium, silicon and oxygen, see Aluminium silicate.
Aluminosilicate refers to materials containing anionic Si-O-Al linkages. Commonly, the associate cations are sodium (Na+), potassium (K+) and Hydrogen (H+). Such materials occur as minerals, coal combustion products[1] and as synthetic materials, often in the form of zeolites. Both synthetic and natural aluminosilicates are of technical significance as structural materials, catalysts, and reagents. Important representativesFeldspar is a common tectosilicate aluminosilicate mineral made of potassium, sodium, and calcium cations surrounded by a negatively charged network of silicon, aluminium and oxygen atoms. Many aluminosilicates are synthesized by reactions of silicates, aluminates, and other compounds. They have the general formula (MAlO2)(SiO2)x(H2O)y where M+ is usually H+ and Na+. The Si/Al ratio is variable, which provides a means to tune the properties.[2] Many of these materials are porous and exhibit properties of industrial value.[3] Naturally occurring microporous, hydrous aluminosilicate minerals are also referred to as zeolites.
