Boron carbide (tsarin sinadarai B4C) abu ne mai matuƙar wuyar yumbu da aka yi amfani da shi a cikin sulke na tanki, rigunan harsashi da aikace-aikacen masana'antu da yawa.Taurinsa na Mohs shine 9.3, kuma shine abu na biyar mafi wuya sananne bayan lu'u-lu'u, cubic boron nitride, mahadi na fullerene da bututun lu'u-lu'u.

Abubuwan da aka bayar na B4C

1) Mafi mahimmancin aikin boron carbide yana cikin taurinsa na ban mamaki (Mohs hardness na 9.3), wanda shine na biyu kawai ga lu'u-lu'u da boron nitride mai siffar sukari, kuma shine mafi kyawun kayan da ba zai iya jurewa yanayin zafi ba;

(2) Girman boron carbide kadan ne, wanda shine mafi sauƙi tsakanin kayan yumbu kuma ana iya amfani dashi a filin sararin samaniya;

(3) Carbide boron yana da ƙarfin shanyewar neutron mai ƙarfi.Idan aka kwatanta da abubuwa masu tsabta B da Cd, yana da ƙananan farashi, kyakkyawan juriya na lalata da kuma kwanciyar hankali mai kyau.Ana amfani da shi sosai a masana'antar nukiliya.Boron carbide yana da kyakkyawan iya sha neutron.Ƙarin haɓakawa ta hanyar ƙara abubuwan B;

(4) Boron carbide yana da kyawawan abubuwan sinadarai.Ba ya amsawa tare da acid, alkalis da mafi yawan mahaɗan inorganic a zafin jiki.Yana lalata sannu a hankali a cikin cakuda hydrofluoric acid-sulfuric acid da hydrofluoric acid-nitric acid.Ita ce mafi kwanciyar hankali sinadarai.Daya daga cikin mahadi;

(5) Carbide boron kuma yana da fa'idodin babban ma'aunin narkewa, madaidaicin ma'auni mai ƙarfi, ƙarancin haɓaka haɓakawa da ingantaccen ƙarfin iskar oxygen;

(6) Boron carbide shima nau'in p-type semiconductor abu ne, wanda zai iya kula da halayen semiconductor koda a yanayin zafi sosai.
