| dc.description.abstractEn | The effect of fluorination on silicate and alumino-silicate minerals has been investigated, in particular on the lepidolite [K(Li,Al)<sub>3</sub> [Si<sub>3</sub>AlO<sub>10</sub>] (F,OH)<sub>2</sub>] of the mica-type. The fluorination techniques included direct F<sub>2</sub>-gas and cold radio-frequency-plasma involving c-C<sub>4</sub>F<sub>8</sub> or O<sub>2</sub>/CF<sub>4</sub> mixtures. The modifications of the surface properties have been followed mostly by XPS. Depending of the fluorination route used, either a reactive etching process involving M–F bonding occurs (direct F<sub>2</sub>-gas; O<sub>2</sub>–CF<sub>4</sub> rf-plasma), or a carbon fluoride deposition takes place (c-C<sub>4</sub>F<sub>8</sub> rf-plasma). | |
