Abstract
Molybdenum nanocrystalline powder particles using electric blasting circuit method after molybdenum circuit destruction were formed. During this process the separate molybdenum-containing particles as products of the explosion reaction with each other and getting thinner during the cooling stage were combining. Their surface is partially oxygenated in argon (Ar) with air addition atmosphere. When cooling is finished the size distribution of the particles had three-modal profile, the most of the particles had 120nm diameter according to electronic microscope data. Oxygenated structures were not observed. Nanopowders were further mixed with sodium-chloride powder (in 5 and 10 mass % concentration) for further activation and pressing into dense tablets.These compact tablets in the nuclear reactor for the radioisotope production are supposed to be irradiated.
