Abstract
Samples of synthetic crystalline diopside were prepared with different volumes of surface phase by varying the time of grinding of each sample, and then investigated using 29Si MAS-NMR. Hydration of the surface, which begins during grinding in laboratory air, allows the surface phase to be detected using 1H- 29Si CP MAS-NMR. The surface phase appears to be structurally similar to diopside glass. Several hours of reaction with aqueous solution promotes the formation of Q 2-(OH) 2, which is indicated by the appearance of a peak in the CP-MAS spectrum at -93 ppm. The progress of hydration appears to be relatively independent of the pH of the aqueous solution.
