B4C nanopowder Boron carbide pauka no ka wiliwili mea
Hōʻike huahana
ʻO ka Boron carbide he mea ʻano ʻole, maʻamau ka pauka hina-ʻeleʻele.He kiʻekiʻe kiʻekiʻe (2.55g/cm³), kahi helu heheʻe kiʻekiʻe (2350 ° C), a me ka paʻa kemika maikaʻi loa a me ka absorption neutron.He paʻakikī loa ka mea, e like me ka paʻakikī o ke daimana, a loaʻa iā ia nā waiwai o ka neutron absorber.Ua alakaʻi kēia i ka hoʻohana ʻana i ka boron carbide ma nā ʻano he nui, e like me ka ikehu nuklea ma ke ʻano he neutron absorber, a me nā mea kūʻokoʻa kūʻokoʻa, ka hana hoʻoikaika ceramic, nā mea pale māmā, a ʻoi aku ka nukle reactor neutron absorber.
