Boron carbide CAS 12069-32-8
Boron carbide (B4C) ndi mankhwala osakhazikika omwe ali ndi kuuma kwakukulu, kukana kuvala, kukhazikika kwamankhwala, komanso kukhazikika kwamafuta ambiri. Amagwiritsidwa ntchito kwambiri ngati zida zolimbikitsira, zosavala, komanso zoteteza m'magawo osiyanasiyana ogwiritsira ntchito. Mtundu wa boron carbide ndi imvi wakuda. Ndi chimodzi mwazinthu zitatu zodziwika bwino kwambiri.

Boron carbide (B4C) ufa umagwiritsidwa ntchito ngati pogaya, ndipo zinthu zopangidwa zimatha kugwiritsidwa ntchito ngati zida zosagwirizana. Amagwiritsidwanso ntchito popanga zida za nyukiliya, zida za ceramic zosagwirizana ndi boron carbide, komanso kupanga zida zolimbana ndi kuvala.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
