Abstract

902,702. Making metal powder. KOHLSWA JERNVERKS A.B. Aug. 17, 1960 [Aug. 20, 1959], No. 28535/60. Addition to 877,917. Class 83 (2). [Also in Group II] In the method of pulverizing and/or decomposing solid materials or materials which are solid at normal temperatures as set forth in the main patent, the shock-waves are generated piezoelectrically or magnetostrictively. The frequency of generation of the shock-waves may be between 20,000 and 1,000,000 vibrations per second but is preferably between 100,000 and 1,000,000 vibrations per second. In the apparatus shown, molten lead 2 (or other metal or alloy) is contained in a crucible 1 which is supported in a transducer bowl 5 provided with metal coverings 6, 7 to which a high-frequency A.C. voltage is applied. The generated shockwaves are focused at a point 13 or small zone at the surface of the molten lead and tear off lead particles which are drawn up through a tube 14 by means of a fan 15. The bowl 5 may be made of barium titanate or quartz. Cooling liquid 9 is circulated between the members 1, 5 and cooling air supplied by one or more tubes 8 cools the underside of the bowl 5. A solid material may be used instead of a molten material and the crucible 1 and cooling layer 9 omitted. Two or more generators working on a common focus point may be used.
