B4C nanopowder Boron carbide vovoka ho an'ny fitaovana welding
Mombamomba ny vokatra
Ny boron carbide dia akora tsy ara-organika, matetika vovoka volondavenona.Izy io dia manana hakitroky avo (2.55g/cm³), teboka levona avo (2350 ° C), ary fitoniana simika tsara sy fisoronana neutron.Ny fitaovana dia tena mafy, mitovy amin'ny hamafin'ny diamondra, ary manana ny fananan'ny neutron absorber.Izany dia nitarika ny fampiasana ny boron carbide amin'ny sehatra maro, toy ny angovo nokleary ho toy ny neutron absorber, ary koa ny mitafy fitaovana mahatohitra, Ceramic dingana fanamafisana, maivana fiadiana, ary indrindra nokleary reactor neutron absorber.
