B4C nanopowder Boron carbide ufa wa zinthu zowotcherera
Mafotokozedwe Akatundu
Micropowder Black B4C Boron Carbide Powder Kwa Ceramic Coating
Boron carbide, yemwenso amadziwika kuti diamondi wakuda, nthawi zambiri amakhala ufa wamitundu.Ndi chimodzi mwazinthu zitatu zolimba kwambiri zomwe zimadziwika (ziwirizi ndi diamondi ndi kiyubiki boron nitride) ndipo zimagwiritsidwa ntchito ngati zida za tank, suti zoteteza zipolopolo ndi ntchito zambiri zamafakitale.Amagwiritsidwa ntchito pazida zosamva kuvala, gawo lolimba la ceramic, makamaka zida zowunikira, zotengera neutron absorbent, e.tc.
