I-B4C nanopowder I-Boron carbide powder kwizinto ze-welding
Ingcaciso yeMveliso
I-Boron carbide yinto engabonakaliyo, idla ngokuba ngumgubo ongwevu-omnyama.Inoxinano oluphezulu (2.55g/cm³), indawo yokunyibilika ephezulu (2350 ° C), kunye nozinzo olugqwesileyo lweekhemikhali kunye nokufunxwa kwe-neutron.Izinto eziphathekayo zinzima kakhulu, zilingana nobunzima bedayimane, kwaye zineempawu ze-neutron absorber.Oku kukhokelele ekusetyenzisweni kwe-boron carbide kwimimandla emininzi, njengamandla enyukliya njenge-nutroni yokufunxa, kunye nezinto ezikwaziyo ukunxiba, isigaba sokuqinisa i-ceramic, isikrweqe esikhaphukhaphu, kwaye ngakumbi i-nutroni yokufunxa inyutroni yenyutroni.
