    Boron Carbide

    IBoron Carbide (B4C), ekwaziwa ngokuba yidayimane emnyama, enobulukhuni beVickers ye>30 GPa, yinto yesithathu enzima emva kwedayimane kunye ne-cubic boron nitride. I-Boron carbide inecandelo eliphezulu lomnqamlezo lokufunxa iineutron (okt iipropathi ezilungileyo zokukhusela iinyutroni), uzinzo kwimitha ye-ionizing kunye neekhemikhali ezininzi. Yimpahla efanelekileyo kwizicelo ezininzi zokusebenza eziphezulu ngenxa yokuhlanganiswa kwayo okukhangayo kweepropati. Ubulukhuni bayo obubalaseleyo buyenza ibe ngumgubo ococekileyo ococekileyo wokukhwela, ukupolisha kunye nokusika ijethi yamanzi kwiintsimbi kunye neekeramics.

    I-Boron carbide yinto ebalulekileyo enobunzima kunye namandla amakhulu omatshini. Iimveliso ze-UrbanMines 'zinococeko oluphezulu kunye namaxabiso akhuphisanayo. Kananjalo sinamava amaninzi ekunikezeni uluhlu lweemveliso ze-B4C. Ndiyathemba ukuba sinokunika iingcebiso eziluncedo kwaye sikunike ukuqonda okungcono kwe-boron carbide kunye nokusetyenziswa kwayo okwahlukeneyo.
