BoronCarbide (B.4C)ni ibikoresho byatoranijwe kugirango bikoreshe imirasire ya kirimbuzi kuko irimo ubwinshi bwa atome ya boron kandi irashobora gukora nka neutron yinjira na detector mumashanyarazi.Boron ya metalloid iboneka muri ceramic B4C ifite isotopi nyinshi, bivuze ko buri atom ifite umubare wa proton imwe ariko umubare wa neutron udasanzwe.Bitewe nigiciro cyacyo gito, kurwanya ubushyuhe, kubura umusaruro wa radioisotope, nubushobozi bwo gukingira imirasire, ceramic B4C nayo ni amahitamo meza yo gukingira ibikoresho munganda za kirimbuzi.
Boron Carbide ni ikintu cyingenzi mu nganda za kirimbuzi kubera ko cyinjira cyane muri neutron (ububiko 760 kuri 2200 m / sek umuvuduko wa neutron). B10 isotope muri boron ifite igice kinini cyambukiranya (ibigega 3800).
Umubare wa atome numero 5 yibintu bya chimique boron yerekana ko ifite proton 5 na electron 5 muburyo bwa atome. B nikimenyetso cyimiti ya boron. Boron naturel igizwe ahanini na isotopi ebyiri zihamye, 11B (80.1%) na 10B (19.9%). Kwinjiza kwambukiranya ibice bya neutron yumuriro muri isotope 11B ni 0.005 ibigega (kuri neutron ya 0.025 eV). Ibyinshi (n, alpha) reaction ya neutron yumuriro ni 10B (n, alpha) 7Li reaction iherekejwe na 0.48 MeV gamma yohereza. Byongeye kandi, isotope 10B ifite reaction yo hejuru (n, alpha) yambukiranya igice cyose cyingufu za neutron. Ibice byambukiranya ibindi bintu byinshi biba bito cyane ku mbaraga nyinshi, nko kuri kadmium. Igice cyambukiranya 10B kigabanuka kimwe n'imbaraga.
Igice kinini cyo kwinjiza ibice bikora nkurushundura runini iyo neutron yubusa ikorwa na fonction nucleaire ikorana na boron-10. Kubera iyo mpamvu, boron-10 irashoboka cyane gukubitwa kurusha andi atome.
Iyi mpanuka itanga isotope ya Boron-11 idahungabana cyane, ivunika muri:
helium atom idafite electron, cyangwa agace ka alfa.
lithium-7 atom
Imirasire ya gamma
Isasu cyangwa ibindi bikoresho biremereye birashobora gukoreshwa mugutanga ingabo ikurura ingufu vuba.
Ibi biranga bituma boron-10 ikoreshwa nkigenzura (uburozi bwa neuron) mumashanyarazi ya kirimbuzi, haba muburyo bukomeye (boron Carbide) nuburyo bwamazi (acide boric). Iyo bibaye ngombwa, boron-10 yinjizwamo kugirango ihagarike irekurwa rya neurone riterwa no gucika uranium-325. Ibi bitesha agaciro urunigi.
