B4C nanopowder boron carbide budada alxanka
Sharaxaada Alaabta
Kaarbiid boron ah waa walax aan organic ahayn, badiyaa budo cawl-madow ah.Waxay leedahay cufnaan sare (2.55g/cm³), bar dhalaalaysa (2350 ° C), iyo xasilloonida kiimikaad aad u wanaagsan iyo nuugista neutronka.Maaddadu waa mid aad u adag, oo la mid ah adayga dheeman, waxayna leedahay sifooyinka nuugista neutron.Tani waxay keentay isticmaalka boron carbide meelo badan, sida tamarta nukliyeerka sida nuugista neutron-ka, iyo sidoo kale xirashada alaabta adkaysiga leh, wajiga xoojinta dhoobada, hubka fudud, iyo gaar ahaan nukleer-ka nuugista neutron.
