Abstract: | By nature minerals are heterogeneous materials for many of their properties. These properties also vary according to composition and structure fluctuations, compared to definitions. Technical minerals are used in applications where their performances depend on intrinsic properties and processing conditions. It is possible to base rankings on simple criteria, allowing estimating the abilities of minerals for each utilisation. The research of the corresponding mechanisms concerns the molecular level. These questions are discussed for kaolins, raw materials for baked clays, talqueous materials and montmorillonites. To cite this article: J. Yvon et al., C. R. Geoscience 334 (2002) 717–730. |
