B4C nanopowder Boron carbide pauta mo mea uelo
Fa'amatalaga o oloa
O le Boron carbide o se mea faʻapitoa, e masani lava o se paʻu efuefu-uliuli.E i ai le maualuga maualuga (2.55g/cm³), maualuga le liusuavai (2350 ° C), ma sili atu le mautu o vailaʻau ma neutron absorption.O le mea e matua faigata lava, tutusa ma le maaa o taimane, ma ei ai meatotino o le neutron absorber.O lenei mea ua mafua ai le faʻaaogaina o le boron carbide i le tele o matata, e pei o le malosi faaniukilia e pei o le neutron absorber, faʻapea foʻi ma mea e faʻafefeteina ai, sera faʻamalosi vaega, ofutau mama, aemaise lava reactor neutron absorber.
