Abstract
The study of a sample of talc from the Trimouins deposit by FTIR, NMR, e.p.r., Moessbauer, XRD and HRTEM techniques is reported, to investigate the extent of minor substitutions in the tetrahedral and octahedral sites. Substitutions cause a deficiency in tetrahedral charge, compensated by an excess octahedral charge, thus giving electroneutrality to the structure. This charge deficiency in the tetrahedral layer layer explains the active interaction that occurs in industry between talc (used as filler) and polymers.
