Niobium boride yog grey hexagonal siv lead ua, uas yog tsuas yog siv hauv cov ntaub ntawv zoo nkauj thiab cov ntaub ntawv superconducting. Ntawm cov ntaub ntawv superconducting, tsuas yog NbB muaj qhov siab superconducting hloov qhov kub thiab txias. Nyob rau tib lub sijhawm, niobium diboride yog cov khoom siv kub ntawm kub kub, txhaws thiab refractory hlau NbN kev sib txuas ntawm cov xov tooj, kev ntub dej zoo thiab kis tau, zoo flux, muaj zog seam puv peev xwm, siab kub weld zog.
