B4C nanopowder Boron carbide phofo bakeng sa thepa ea ho tjheseletsa
Tlhaloso ea Sehlahisoa
Boron carbide ke ntho e sa tloaelehang, hangata e le phofo e bohlooho-e ntšo.E na le sekhahla se phahameng (2.55g/cm³), sebaka se phahameng sa ho qhibiliha (2350 ° C), le botsitso bo botle ba lik'hemik'hale le ho monya nyutrone.Boitsebiso bo thata haholo, bo lekana le boima ba daemane, 'me bo na le thepa ea neutron absorber.Sena se lebisitse ts'ebelisong ea boron carbide mafapheng a mangata, joalo ka matla a nyutlelie joalo ka mohanyi oa nyutrone, hammoho le thepa e hanyetsanang le ho roala, mokhahlelo oa matlafatso oa ceramic, lihlomo tse bobebe, haholo-holo sehanyi sa nuclear reactor neutron.
