METHOD FOR BORON RECOVERY FROM BORON CARBIDE Russian patent published in 1999 - IPC

Abstract RU 2137227 C1

FIELD: nuclear power engineering. SUBSTANCE: method involves transfer of boron to gaseous phase in the form of boron halide by halogen and/or halide gas mixture containing 0.0001-10 volume percent of oxygen and/or oxygen-containing compounds. Coefficients of cleaning by this method are sufficient for producing boron of natural-background activity. EFFECT: improved properties of recovered boron. 1 tbl
