Preparation of calcium and magnesium fluorides with extended surface areas using β-cyclodextrin as a structure-forming agent

A new method for the synthesis of calcium and magnesium fluorides with high surface areas is proposed; the fluorides obtained by the decomposition of β-cyclodextrin–metal trifluoroacetate mixtures have surface areas of about 80 and 60 m2 g−1 for CaF2 and MgF2, respectively.
