I-B4C nanopowder I-Boron carbide powder yezinto zokushisela
Incazelo Yomkhiqizo
I-Boron carbide iyisithako esingaphili, ngokuvamile impushana empunga-mnyama.Inokuminyana okuphezulu (2.55g/cm³), indawo yokuncibilika ephezulu (2350 ° C), kanye nokuzinza okuhle kakhulu kwamakhemikhali kanye nokumuncwa kwe-neutron.Impahla inzima kakhulu, ilingana nobulukhuni bedayimane, futhi inezakhiwo ze-neutron absorber.Lokhu kuholele ekusetshenzisweni kwe-boron carbide emikhakheni eminingi, njengamandla enuzi njengesimunca i-neutron, kanye nezinto ezikwazi ukumelana nokugqoka, isigaba sokuqinisa i-ceramic, izikhali zempi ezingasindi, futhi ikakhulukazi i-nuclear reactor neutron absorber.
