Abstract
Solid state 27Al n.m.r. spectroscopy of various aluminosilicates (zeolites, clays, amorphous SiO2–Al2O3) shows that upon thermal or hydrothermal treatment a line appears at 30 p.p.m.; the position of this line suggests that penta-co-ordinated Al is present in all these aluminosilicates.Keywords
