Ntau tshaj 30 GPa
Vickers hardness ntawm Boron Carbide yog ntau tshaj 30 GPa. Tus nqi hardness no ua rau Boron Carbide ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws paub, thib ob tsuas yog cubic boron nitride thiab pob zeb diamond. Lub hardness ntawm Boron Carbide muab nws cov txiaj ntsig tseem ceeb hauv ntau yam kev siv, suav nrog tab sis tsis txwv rau lub tank armor, tsho tiv thaiv mos txwv, lub cav tawg hmoov, thiab ntau yam kev lag luam. Nws cov hardness siab tsis tsuas yog ua rau nws zoo tagnrho hnav-resistant khoom, tab sis kuj ua hauj lwm raws li ib tug neutron absorber nyob rau hauv lub nuclear zog teb los tswj tus nqi ntawm nuclear fission thiab xyuas kom meej kev ruaj ntseg ntawm nuclear reactors. 12
Lub cev muaj zog ntawm Boron Carbide kuj suav nrog nws qhov ntom ntom ntawm 2.52 g / cm³, melting point ntawm 2445 degree, thiab hardness xws li 2900 - 3580 Kg / mm² (Knoop 100 g). Cov khoom no ua ke muab Boron Carbide stability thiab kav ntev hauv qhov kub thiab txias ib puag ncig, ua rau nws muaj ntau yam khoom siv engineering.
Tsis tas li ntawd, kev tshawb fawb txog kev tsim khoom thiab kev siv cov boron carbide tseem tsis tu ncua, xws li kev npaj ua haujlwm siab B4C-LaB6 puas ceramics los ntawm kev kub ceev sintering thev naus laus zis los txhim kho nws cov tawv tawv thiab lwm yam khoom siv tshuab thiab nthuav dav nws cov ntawv thov.
