摘要： A method of forming metal spheres includes ejecting a precisely measured droplet of molten metal from a molten metal mass, buffering the molten metal droplet to reduce the internal kinetic energy of the droplet without solidifying the droplet and cooling the buffered droplet until the droplet solidifies in the form of a metal sphere. An apparatus for fabricating metal spheres includes a droplet generator that generates a droplet from a molten metal mass, a buffering chamber that receives the droplet from the droplet generator, and diminishes internal kinetic energy of the droplet without solidifying the droplet, and a cooling drum that receives the droplet from the buffering chamber, and cools the droplet to the extent that the droplet solidifies into a metal sphere. The apparatus may further include a collector arrangement that receives the metal spheres from the cooling drum and makes the metal sphere available for collection.

摘要： Rare earth magnetic alloy fine powders are manufactured by placing a mixture of a rare earth metal and a transition metal as raw materials in a crucible, induction heating it in an Ar gas atmosphere, melting metal elements contained in the above mixture, injecting an Ar gas at a predetermined pressure from above the molten alloy to expel the above molten alloy in a downward direction from the nozzle port of the above crucible, and applying a jet stream of an inert gas to the above expelled molten alloy to collide the above expelled molten alloy with the above inert gas so as to scatter the above molten alloy and solidify it by quenching. A rare earth bond magnet and a rare earth sintered magnet are produced using rare earth magnetic alloy fine powders obtained by the above process, which is rarely oxidized on the surface, almost spherical and uniform in diameter.

摘要： In a high-speed fabrication process for producing highly uniform metallic microspheres, a molten metal is passed through a small orifice, producing a stream of molten metal therefrom. A series of molten metal droplets forms from the break up of the capillary stream. To achieve high uniformity of the spheres and avoid defects, the droplets are cooled before being captured. Separating the droplets, by causing them to travel in different paths than their adjacent droplets, helps to facilitate the cooling of the droplets. The droplets can be separated by electrostatically charging them as they break off from the capillary stream. The droplets are then passed through an electric field, which can be produced by a pair of deflection plates. The droplets are dispersed by varying the electric field—e.g., by rotating the plates or by varying the voltage applied thereto—or by varying the electrostatic charge of the droplets. Advantageously, the droplets can be actively cooled in flight by passing them through a cryogenic gas chamber.

摘要： An apparatus and method for the production of small, uniform sized droplets. The apparatus is a droplet generator including a housing defining a chamber for holding a material to be ejected therefrom, an inlet and a droplet outlet communicating with the chamber. The housing is coupled to a pressurizing system connected to the inlet for applying pressure pulses to the chamber. The housing includes a vent in communication with the chamber for relieving pressure in the chamber. The vent has an effective size so that during application of the pressure pulse the chamber is pressurized to a pressure effective to eject a droplet of the material therefrom and thereafter the chamber is vented through the vent at a rate sufficient to prevent further discharge of droplets. The droplet generator produces molten metal or alloy droplets and is particularly suitable for generating single droplets on demand in manufacturing techniques using droplet deposition. It is also useful for production of spherical microspheres and uniform sized powders, and dispensing of precise quantities of materials such as adhesives and pharmaceuticals.

摘要： A method of rapidly cooling molten mixtures of alkali metal alloys in which the metal components of said alloys have a wide divergence of melting points that result in separation of the alkali metals during cool down. A calcium-sodium alloy is produced in an electrolysis cell. A method of high pressure atomization of the calcium-sodium alloy and its subsequent rapid cooling produces a calcium nodular particulate that is encased in a sodium flocculant.
