B4C nanopowder Boron carbide foda don kayan walda
Bayanin Samfura
Boron carbide wani abu ne wanda ba a iya gani ba, yawanci foda mai launin toka-baki.Yana da girma mai yawa (2.55g/cm³), babban wurin narkewa (2350 ° C), da kyakkyawan kwanciyar hankali na sinadarai da sha neutron.Kayan yana da wuyar gaske, daidai yake da taurin lu'u-lu'u, kuma yana da kaddarorin mai ɗaukar neutron.Wannan ya haifar da amfani da sinadarin boron carbide a fagage da dama, kamar makamashin nukiliya a matsayin abin sha na Neutron, da kuma sanya kayan da ba zai iya jurewa ba, lokacin karfafa yumbura, sulke mai nauyi, musamman ma na'urar samar da makamashin nukiliya.
