METHOD FOR THE AQUEOUS-PHASE SYNTHESIS OF LAYERED DOUBLE HYDROXIDE-TYPE COMPOUNDS

摘要

The invention relates to a method for the aqueous-phase synthesis of layered double hydroxide-type compounds from at least partially solid precursor elements. The inventive method is characterised in that it consists in: using natural minerals or industrial by-products as precursor elements; at least partially solubilising the precursor elements, such as to obtain a solution of divalent and trivalent cations; and performing a coprecipitation with a base comprising said solution of cations.
