ResumenThe process for obtaining a micro- or nano- particulated composite comprises: adding at least two Compounds C to a fluid A, with one of said compounds being insoluble in said fluid A; adding a fluid B, such that said fluid B at working pressure Pw is miscible with said mixture A and acts as a co-solvent to form a solution AB, in which said pressure Pw is greater than atmospheric pressure but lower than the critical pressure Pc of the solution AB, and the working temperature Tw is lower than the critical temperature of the solution AB; and reducing the pressure Pw of said solution AB to atmospheric pressure, so that there occurs an increase of supersaturation that is ideally homogeneous throughout the solution AB and causes precipitation of the Compounds C. It also relates to the composite obtained.
