Comprises a) dissolving a compound C in a fluid A to provide a solution A; b) Thermostatization of said solution A to a temperature ranging between -50° C. and 200° C.; c) Adding a fluid B to said solution A until a pressure P is obtained, and is characterized in that said fluid B at a pressure P is miscible with said solution A, and acts as a co-solvent to form a solution AB; and d) Reduce the pressure of said solution AB so as to produce the precipitation of said compound C. The method permits to obtain particles of average size less than 20 mum, generally less than 10 mum, with a narrow distribution ranging between 1 and 100 mum, generally ranging between 1 and 20 mum, and from a solution, and not a mix, that contains the compound to be precipitated.
