Method for producing small metal balls approximately equal in diameter |
摘要 |
In order to develop a method for producing at least approximately ball-shaped metallic particles at least almost equal in diameter such that a greater yield of particles at least almost equal in diameter is achieved than in known methods, it is suggested that a continuous stream of liquid metal is acted on locally by compressional vibrations that thereby cross-sectional constrictions are formed in the stream at a distance from each other in longitudinal direction of the stream which lead to the dissection of the stream and that the segments of the dissected stream adopting a ball shape due to the surface tension of the liquid metal are cooled to solidify the liquid metal.
