Apparatus (10) and method for producing pigment nano-particles (12). One embodiment of the apparatus (10) may comprise a furnace (16) having a vapor region (18), the furnace (16) vaporizing a pigment precursor material (14). A precipitation conduit (20) open to the vapor region (18) of the furnace (16), the precipitation conduit (20) receiving vapor (22) from the vaporized pigment precursor material (14.prime.). A collection fluid port (30) opening into the precipitation conduit (20), the collection fluid port (30)delivering a collection fluid (32) into contact with the vapor (22) in the precipitation conduit (22), the vapor (22) condensing to form the pigment nano-particles (12). A collection system (24) in fluid connection with the precipitation conduit (20), the collection system (24) collecting the pigment nano-particles (12) in the collection fluid (32).

L'invention concerne un appareil (10) et un procédé permettant de produire des nanoparticules de pigment (12). Un mode de réalisation dudit appareil (10) peut comprendre un four (16) comportant une zone de vapeur (18), le four (16) vaporisant un matériau précurseur de pigment (14). Un conduit de précipitation (20) donnant sur la zone de vapeur (18) du four (16) reçoit la vapeur (22) provenant du matériau précurseur de pigment vaporisé (14'). Un port de fluide de collecte (30) donnant dans le conduit de précipitation (20) fournit un fluide de collecte (32) et met ce dernier en contact avec la vapeur (22) contenue dans le conduit de précipitation (20), la vapeur (22) entrant en condensation pour former les nanoparticules pigmentaires (12). L'invention a également trait à un système de collecte (24) placé en liaison fluidique avec le conduit de précipitation (20), qui recueille les nanoparticules de pigment (12) contenues dans le fluide de collecte (32).
