| 1. A supersonic kinetic spray nozzle comprising:
a converging region and a diverging region separated by a throat, said diverging region extending from said throat to an exit
end; and
at least a portion of said diverging region adjacent said throat having a cross-sectional expansion rate of at least 1.0 millimeters
squared per millimeter;
wherein said portion is located within a first one third of a length of said diverging region adjacent to said throat and
wherein said cross-sectional expansion rate decreases between said first one third and said exit end of said diverging region.
