Boron Carbide
Boron Carbide (B4C), wanda kuma aka sani da black lu'u-lu'u, tare da taurin Vickers na> 30 GPa, shine abu na uku mafi wahala bayan lu'u-lu'u da boron nitride cubic. Boron carbide yana da babban ɓangaren giciye don ɗaukar neutrons (watau kyawawan kaddarorin kariya daga neutrons), kwanciyar hankali ga ionizing radiation da yawancin sinadarai. Abu ne mai dacewa don aikace-aikacen manyan ayyuka da yawa saboda haɓakar halayensa masu kyau. Ƙarfinsa na ban mamaki ya sa ya zama foda mai dacewa don lapping, polishing da yanke jet na ruwa na karafa da tukwane.
Boron carbide abu ne mai mahimmanci tare da nauyi mai nauyi da ƙarfin injina. Kayayyakin UrbanMines suna da tsafta mai yawa da farashin gasa. Hakanan muna da gogewa sosai wajen samar da kewayon samfuran B4C. Da fatan za mu iya ba da shawarwari masu amfani da kuma ba ku kyakkyawar fahimta game da boron carbide da fa'idodinsa iri-iri.
