METHOD OF REGENERATING BORON ELEMENTAL, ENRICHED IN BORON-10 ISOTOPE, FROM BORON-FILLED POLYMERS Russian patent published in 2019 - IPC G01N23/06 

FIELD: chemistry.

SUBSTANCE: invention relates to recovery of expensive components from materials from disassembly of articles for secondary use. Essence consists in the fact that boron enriched in boron-10 isotope regeneration from boron-filled polymer wastes is performed by successive operations: separation of fragments of parts from disassembly through thickness, identification of fragments by polymer binder, X-ray identification and separation of fragments by isotope composition, thermal destruction of polymer binder in an inert gas medium, obtaining required fraction of boron powder by screening on sieves with corresponding cell values, analysing obtained product for compliance with technical requirements, chemical purification of the product if necessary, enlargement of a fraction which does not comply with technical requirements, by high-temperature sintering in a vacuum or in an inert gas medium with subsequent crushing.

EFFECT: technical result is obtaining (regeneration) of boron powder enriched with boron-10 isotope from wastes of boron-filled polymers without changing its chemical composition and degree of enrichment with respect to boron-10 isotope.
