FIELD: powder metallurgy, namely production of particles of radioactive metals or alloys. ^ SUBSTANCE: method comprises steps of preparing by melting melt metal or alloy mass; forming stream of such mass; spraying it and sharply cooling particles. According to invention melting is realized in inert gas atmosphere. Stream of melt metal is formed by means of nozzle. Stream is sprayed due to its contact with cooling liquid subjected to centrifugal rotation. Melt metal stream is surrounded by inert gas jacket till its contact with cooling liquid. Apparatus for performing the method includes unit for melting radioactive metal or alloy in inert gas atmosphere; units for subjecting cooling liquid to centrifugal rotation and for surrounding melt metal stream with inert gas jacket till contact of stream with cooling liquid. Stream of melt metal is formed by means of nozzle. Invention provides significantly lowered oxygen content in powder, reduced pyrophoric property of powder. ^ EFFECT: minimized losses of process of forming particles, decreased risk of vapor explosion. ^ 11 cl, 1 dwg |
