Abstract: To produce products from metal, such as powders, foils, coatings and molded parts, such as pins, pipes or sheets, from metal in the form of a semifinished product (15), the metal of the semifinished product (15) is melted by an inductive magnetic field (12), atomized and allowed to solidify in a chamber (25) into a powder or sprayed onto a carrier and hardened on the carrier. The molten metal is supplied in a gas nozzle (10) which is made either as a Laval nozzle or as a Venturi nozzle, as a film (21) which is stabilized by gas flows (14), and is then atomized by other gas flows (13).

Abstract: The invention relates to a process for producing largely nonferrous metal chalcogenides or arsenides which can be easily carried out in terms of process engineering in an environmentally-friendly manner. This is because in a single process step the desired, largely nonferrous metal chalcogenide or arsenide is obtained from a nonferrous metal powder by reaction with reactants selected from the group sulfur, selenium, tellurium, and arsenic by grinding in a reaction mill in an inert atmosphere.

Abstract: A method for atomizing liquid films to fine droplets (2), wherein the liquid (2) is discharged from an elongate slotted nozzle (3) in the shape of a straight film. The outlet opening of the slotted nozzle (3) is located inside a linear Venturi nozzle (5) in whose divergent section linear gas outlet openings (7) (Laval nozzles) are provided and impinged upon by gas (6). The negative pressure produced in the area of the Laval nozzles (7) draws in gas flows (4) from the gas chambers (1), located at both sides of the liquid film and delimited by the convergent section of the Venturi nozzle (5). Said gas flows stabilize the liquid film in such a manner that it is atomized to a tent-shaped cone of liquid droplets only after passage of the narrowest point of the Venturi nozzle (5).
