Abstract: A device is provided for atomizing a molten metal stream whereby a first jet of an atomizing fluid is directed to a molten metal and a second jet is directed to the combined stream of the molten metal and first jet of atomizing fluid; the second jet impinges the combined stream at a certain angular relationship to the molten metal stream; as a result of the specific arrangement of the jets embodied in particular nozzles and their orientation, a fine, very uniform powder is obtained which consists of smooth, substantially spherical particles; the device is operational without any substantial splash-back and the amount of molten metal which may be atomized on basis of the fluid for operating of the jets constitutes an advantageous aspect of the device.
