Aluminosilicate refers to materials containing anionic Si-O-Al linkages. Commonly, the associate cations are sodium (Na+), potassium (K+) and protons (H+). Such materials occur as minerals 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.

Feldspar 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.[1] Many of these materials are porous and exhibit properties of industrial value.[2] Naturally occurring microporous, hydrous aluminosilicate minerals are also referred to as zeolites.
