Boron carbide yana da kyakkyawan juriya na lalata da kuma juriya mai yawan zafin jiki.Ba ya amsawa tare da acid, alkalis da mafi yawan mahaɗan inorganic a zafin jiki.Akwai jinkirin lalatawa a cikin sulfuric acid, gaurayawan acid na hydrofluoric acid-nitric acid.A hadawan abu da iskar shaka dauki m ba ya faruwa a kasa 600 ° C, da kuma lokacin da zazzabi ne sama da 600 ° C, wani B2O3 fim da aka kafa saboda surface hadawan abu da iskar shaka, hana kara hadawan abu da iskar shaka.

Boron carbide za a iya ƙara zuwa carbonaceous refractory a matsayin antioxidant, wanda ba kawai inganta thermal girgiza juriya na refractory, amma kuma kare refractory daga infiltration na karfe da slag, da kuma hana carbon a cikin carbonaceous refractory daga zama oxidized.Dalilin da ya sa zai iya taka wannan rawa shi ne cewa lokacin da boron carbide ya zama oxidized, zai yi hulɗa tare da kayan tushe don samar da wani lokaci na ruwa ko gas, ta yadda zai hana carbon a cikin carbonaceous refractory daga zama oxidized da kuma tsawaita rayuwar sabis na carbon. - dauke da refractory.
