B4C nanopwder Pùdar carbide boron airson stuth tàthaidh
Tuairisgeul toraidh
Is e stuth neo-organach a th’ ann am boron carbide, mar as trice pùdar glas-dubh.Tha dùmhlachd àrd (2.55g / cm³), ìre leaghaidh àrd (2350 ° C), agus seasmhachd ceimigeach sàr-mhath agus sùghadh neutron.Tha an stuth gu math cruaidh, co-ionann ri cruas daoimean, agus tha feartan sùghaidh neutron aige.Tha seo air leantainn gu bhith a’ cleachdadh boron carbide ann an iomadh raon, leithid lùth niuclasach mar sùghaidh neutron, a bharrachd air stuthan a tha an aghaidh caitheamh, ìre ath-neartachaidh ceirmeag, armachd aotrom, agus gu sònraichte sùghadair neutron reactair niùclasach.
