Ọkpụkpụ boron carbide
Boron Carbide (B4C), makwaara dị ka diamond ojii, nke nwere ike siri ike nke Vickers> 30 GPa, bụ ihe nke atọ kachasị sie ike na-esote diamond na cubic boron nitride. Boron carbide nwere akụkụ obe dị elu maka nnabata nke neutrons (ya bụ ezigbo ihe nchebe megide neutron), nkwụsi ike na radieshon ionizing na ọtụtụ kemịkalụ. Ọ bụ ihe kwesịrị ekwesị maka ọtụtụ ngwa arụmọrụ dị elu n'ihi nchikota mara mma ya. Isi ike ya pụtara ìhè na-eme ka ọ bụrụ ntụ ntụ abrasive kwesịrị ekwesị maka ịcha, polishing na mmiri jet ịcha ọla na seramiiki.
Boron carbide bụ ihe dị mkpa nke nwere ike dị fechaa na nnukwu igwe. Ngwaahịa UrbanMines nwere ịdị ọcha dị elu yana ọnụ ahịa asọmpi. Anyị nwekwara ahụmịhe dị ukwuu n'inye ngwaahịa B4C dị iche iche.
