Patent GB-2094748-A (GB)
Title: Forming metal microspheres
IPC: B01J13/02
Filed: 1982-03-05
Abstract: Hollow metal microspheres (17) made from film forming metal compositions. The hollow metal microspheres (17) are used to make superior high strength light weight structural materials. The hollow metal microspheres (17) are made by forming a liquid film of molten film forming metal composition across a coaxial blowing nozzle (5), applying a blowing gas (10) at a positive pressure on the inner surface of the metal film to blow the film and form an elongated cylinder shaped liquid film (12) of molten metal. A transverse jet (13) is used to direct an inert entraining fluid (14) over and around the blowing nozzle (5) at an angle to the axis of the blowing nozzle. The entraining fluid (14) as it passes over and around the blowing nozzle (5) fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle. The continued movement of the entraining fluid (14) over the elongated cylinder (12) produces asymmetric fluid drag forces on the cylinder and closes and detaches the elongated cylinder from the coaxial blowing nozzle and the detached cylinder by the action of surface tension forms into a spherical shape (17). Quench nozzles (18) are disposed below and on either side of the blowing nozzle (5) and direct cooling fluid (19) at and into contact with the molten metal microspheres (17) to rapidly cool and solidify the molten metal to form a hard, smooth hollow metal microsphere (17). The hollow metal microspheres (17) can be made to contain a thin metal coating (20) deposited on the inner wall surface of the microspheres by using a metal vapor as a blowing gas or by adding to the blowing gas small dispersed metal particles and/or gases or organo metal compounds and decomposing the organo metal compounds. The metal microspheres can be used to make improved insulation materials and insulating systems. The hollow metal microspheres (17) can be used as filler materials in plastics, in plastic foam compositions, in rubber and rubber compositions, and in metal compositions. The hollow metal microspheres (17) can also be made in the form of filamented metal microspheres (17a, b and c) with a thin metal filament (17d) connecting adjacent metal microspheres (17).
