ABSTRACT:
The present invention is a method for producing a silver halide emulsion. The precipitation of the emulsion is carried out away from the rotary agitator. The reactant solutions are introduced into the reactor very close to the tip of one or more ultrasonic horns that are placed away from the agitator. The ultrasonic horns are efficient sources for controlling micromixing, while the agitator controls the macromixing in the reactor.
