Abstract

A structural analysis of talc ground under dry atmospheric conditions for different grinding times has been made by X-ray diffraction. The SiO₄ tetrahedra are found to remain unchanged in the ground talc samples by analysing the radial distribution function. On the other hand, with an increase of the grinding time a change in oxygen coordination number around magnesium has been quantitatively confirmed. This variation is attributed to the change of a hydroxyl induced by the prolonged grinding.
