Abstract

MAS-NMR spectroscopy has been used to probe the crystallographic environment of Si, Al, F and H in 14 natural talc samples from different localities and with varying small amounts of iron (Fe (sub 2) O (sub 3(tot)) < 2 wt %). The Fe induces strong variations in NMR spectra, and even low amounts can be used as an indirect NMR parameter to characterize in detail the crystal chemistry of talc. Conversely, their correlation with full width at half height in MAS-NMR spectra for (super 29) Si, (super 27) Al, (super 1) H and (super 19) F obtained from these 14 specimens allow for rapid estimation of the total iron content. By recording Moessbauer, NIR and NMR spectra, an accurate structural formula can be obtained for talc, which is a necessary parameter for use in specific industrial applications.
