B4C nanopowder Boron carbide ntụ ntụ maka ịgbado ọkụ ihe
Nkọwa ngwaahịa
Boron carbide bụ ihe inorganic, na-abụkarị ntụ ntụ ntụ ojii.Ọ nwere njupụta dị elu (2.55g/cm³), ebe mgbaze dị elu (2350 Celsius C), yana ezigbo nkwụsi ike kemịkalụ na nnabata neutron.Ihe ahụ siri ike nke ukwuu, hà nhata nke siri ike nke diamond, ma nwee njirimara nke neutron absorber.Nke a ebutela iji boron carbide mee ihe n'ọtụtụ mpaghara, dị ka ike nuklia dị ka ihe na-ekpo ọkụ neutron, yana iyi ihe ndị na-eguzogide ọgwụ, usoro nkwado seramiiki, ngwa agha dị fechaa, na karịsịa ihe na-eme ihe na-emepụta ihe neutron.
