Abstract: A device for forming spherical particles may include a receiving chamber having a heating portion and a cooling portion. Wire segments may travel in a free fall through the receiving chamber. While falling through the heating portion, wire segments may be heated to form spherical particles in response to exposure to microwave electromagnetic radiation. While falling through the cooling portion, formed spherical particles cool.
