Budada Madaw ee B4C Boron Carbide Budada Dahaarka dhoobada ah

Boron carbide, oo loo yaqaan dheeman madow, sida caadiga ah waa budo midab leh. Waa mid ka mid ah saddexda shay ee ugu adag ee loo yaqaan (labada kale waa dheeman iyo boron nitride cubic) waxaana loo isticmaalaa hubka taangiga, suudadka aan xabadu karin iyo codsiyada warshadaha badan.Waxa loo isticmaalaa agabka xidhashada u adkaysta, wejiga xoojiyey dhoobada, gaar ahaan hubka fudud, nuugista neutron reactor, etc
