Abstract
Method for producing pigment nano-particles may include vaporizing a pigment precursor material; drawing the vaporized pigment precursor material into a precipitation conduit; contacting the vapor in the precipitation conduit with a collection fluid at a first location within the precipitation conduit, the contacting cooling the vapor and precipitating pigment nano-particles, the contacting occurring in the absence of a temperature change in the vapor at locations within the precipitation conduit that are upstream of the first location; and collecting the pigment nano-particles in a collection fluid.
