Alkaline solutions containing both silicate and aluminate ions are of considerable research interest inter alia because of their involvement in the synthesis of zeolites. 27Al NMR spectra of alkaline aluminosilicate solutions generally show a maximum of five broad bands. In the present work, we use 27Al NMR to characterize aluminosilicate solutions with different Al/Si ratios using 2-hydroxyethyl(trimethyl)ammonium as a cation template, no alkaline metals are used for preparation of aluminosilicate solutions. To understand the reaction between silicate and aluminate ions in this system, the evolutions of 27Al NMR spectra with time are investigated.
