METHOD OF PRODUCING BORON-11 ISOTOPE AND COMPOUNDS BASED THEREON Russian patent published in 2014 - IPC G21G1/06 

FIELD: physics, atomic power.

SUBSTANCE: invention relates to nuclear engineering, particularly to production of stable isotopes using neutron beams, and can be used in the electronic industry when producing semiconductor silicon structures using ion implantation techniques, as well as nuclear engineering when designing neutron retarding elements. The disclosed method includes making a starting target from a substance which contains a mixture of boron-10 and boron-11 isotopes, irradiating the target with neutron flux to the required or complete burn-off of the boron-10 isotope and extracting the ¹¹B isotope from the substance.

EFFECT: obtaining boron and compounds thereof with high, more than 99,9%, enrichment on the ¹¹B isotope and high degree of purity.
