摘要： A cryogenic fluid in the liquid phase is put in contact with a metal material maintained in a closed treating vessel, the cryogenic fluid which contains the solid particles formed is exhausted from the vessel, and the solid particles are separated from the cryogenic fluid and collected. The metal material is heated by induction heating with a high-frequency current and maintained in levitation in the cryogenic liquid. The process is applicable to the production of ultra-fine powders from metals which are only slightly volatile.
