B4C nanopowder Boron carbide ufa wa zinthu zowotcherera
Mafotokozedwe Akatundu
Boron carbide ndi chinthu chosasinthika, nthawi zambiri ndi ufa wakuda.Ili ndi kachulukidwe kwambiri (2.55g/cm³), malo osungunuka kwambiri (2350 ° C), komanso kukhazikika kwamankhwala komanso kuyamwa kwa neutroni.Zinthuzo ndizovuta kwambiri, zofanana ndi kuuma kwa diamondi, ndipo zimakhala ndi mphamvu ya nyutroni.Izi zapangitsa kugwiritsa ntchito boron carbide m'magawo ambiri, monga mphamvu ya nyukiliya monga chotengera cha nyutroni, komanso kuvala zinthu zosagwirizana, gawo la ceramic reinforcement, zida zankhondo zopepuka, makamaka zida zanyukiliya za neutron absorber.
