Niobium boride yog grey hexagonal siv lead ua, feem ntau yog siv los ua cov khoom siv zoo ceramic thiab cov khoom siv superconducting.
Ntawm cov khoom siv superconducting, tsuas yog NbB muaj kev hloov pauv ntawm qhov kub thiab txias. Nyob rau tib lub sijhawm, Niobium boride yog cov khoom siv raw ntawm cov khoom siv kub kub. Tom qab cov khoom siv brazing yog brazed nrog cov hlau refractory NbN, lub wettability thiab spreadability yog zoo heev solder fluidity, muaj zog filling muaj peev xwm, thiab zoo heev kub siab zog ntawm weld.
