BoronCarbide (B4C)waa maadada la door biday codsiyada nuugista shucaaca nukliyeerka sababtoo ah waxay ka kooban tahay atamyada boron-ka oo aad u badan waxayna u shaqayn kartaa sida nuugista neutron-ka iyo qalabka wax-qabad ee nukliyeerka.Boronka metalloid ee laga helo dhoobada B4C waxay leedahay isotopes badan, taas oo macnaheedu yahay in atamka kasta uu leeyahay tiro isku mid ah oo borotoon ah laakiin tiro gaar ah oo neutrons ah.Sababtoo ah qiimaha hooseeya, caabbinta kulaylka, la'aanta wax soo saarka radioisotope, iyo awoodda ilaalinta shucaaca, B4C ceramic sidoo kale waa doorasho weyn oo loogu talagalay alaabta gaashaanka ee warshadaha nukliyeerka..
Boron Carbide waa shay muhiim u ah warshadaha nukliyeerka sababtoo ah qaybta nuugista neutron-ka sare ee qaybta (760 barns at 2200 m/sec neutron xawaaraha neutron). Isotope-ka B10 ee boron wuxuu leeyahay qayb weyn oo iskutallaab ah (3800 barns).
Nambarka atomiga 5 ee curiyaha kiimikada boron wuxuu tilmaamayaa inuu leeyahay 5 borotoon iyo 5 elektaroonig ah qaab dhismeedkiisa atomiiga. B waa astaanta kiimikada boron. boron dabiiciga ah wuxuu ka kooban yahay laba isotopes oo deggan, 11B (80.1%) iyo 10B (19.9%). Qaybta nuugista ee neutron-ka kulaylka ee isotope 11B waa 0.005 barns (loogu talagalay neutron-ka 0.025 eV). Inta badan (n, alfa) falcelinta neutrons-ku waa 10B (n, alfa) 7Li falcelin oo ay la socoto 0.48 MeV gamma qiiqa. Intaa waxaa dheer, isotope 10B waxay leedahay falcelin sare (n, alfa) qaybta falcelinta oo ay weheliso dhammaan tamarta neutron-ka. Qaybaha isku-dhafan ee inta badan walxaha kale waxay noqdaan kuwo aad u yar marka loo eego tamarta sare, sida kiiska cadmium. Qaybta iskutallaabta ee 10B waxay hoos ugu dhacdaa keli ahaan tamar.
Qaybta nuugista xudunta wayn waxay u shaqaysaa sidii shabag wayn marka neutronka xorta ah ee uu soo saaro fission nukliyeerka uu la falgalo boron-10. Taas awgeed, boron-10 aad ayey ugu dhowdahay in lagu dhufto marka loo eego atamka kale.
Isku dhacani waxa uu soo saaraa isotope aan deganayn oo ah Boron-11, kaas oo u kala jaba:
atamka helium oo aan lahayn elektaroonno, ama qayb alfa ah.
atom-7 lithium ah
Shucaaca Gamma
Leedhka ama walxo kale oo culus ayaa loo isticmaali karaa in lagu bixiyo gaashaan si dhakhso ah u nuugaya tamarta.
Tilmaamahani waxay u oggolaanayaan boron-10 in loo isticmaalo nidaamiye (sunta neuron) ee reactors nukliyeerka, labadaba qaabkeeda adag (boron Carbide) iyo qaabka dareeraha (boric acid). Marka loo baahdo, boron-10 ayaa la geliyaa si loo joojiyo sii deynta neurons-ka ee ay sababto fiska uranium-325. Tani waxay ka takhalusaysaa falcelinta silsiladda.
