[Evidence of mineral impurities in talc]

Polarizing microscopy, X-ray powder diffraction and differential thermal analysis can be used to detect small amounts of minerals which may occur in talcs as impurities. The characteristic features of chlorite, asbestos, magnesite, quartz and other minerals recognizable through these methods are des

Talc is a hydrous magnesium 2:1 phyllosilicate mineral with a chemical composition of Mg 3 Si 4 O 10 (OH) 2, which corresponds to a theoretical content of 63.5% de SiO 2; 31.7% of MgO and 4.8% of H 2 O. Although the composition of talc usually stays close to this formula, some substitutions occur.

Moreover, all of the measurements were focused on large talc particles to avoid the analysis of accessory minerals. On this basis, it is reasonable to assume that the remaining metal oxides recorded in the analysis (e.g. Fe 2 O 3) originate from the talc crystal lattice rather than from impurities (Al–Fe-bearing phases).
