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： A method for producing semiconductor or metal particles comprises the steps of: storing a semiconductor or metal melt in a crucible having a nozzle; supplying a gas comprising at least one selected from the group consisting of He, Ne, Ar, Kr and Xe into the crucible such that the pressure of the supplied gas in a space over the melt in the crucible is higher than the pressure of a gaseous phase into which the melt is dropped; dropping the melt from the nozzle into the gaseous phase by the pressure of the gas to form liquid particles; and solidifying the liquid particles in the gaseous phase to obtain semiconductor or metal particles. The crucible comprises at least one selected from the group consisting of hexagonal BN, cubic BN, Si3N4, TiB2, ZrB2, zirconia and stabilized zirconia at least near the nozzle. Alternatively, the crucible comprises quartz glass at least near the nozzle and has a heat-resistant support member for suppressing deformation caused by a decrease in viscosity of the quartz glass at high temperatures.

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 fieldnulle.g., by rotating the plates or by varying the voltage applied theretonullor 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.
