Niobium buride yog qhov grey hexagonal crystal, feem ntau yog siv los ua cov khoom zoo ceramic raw thiab cov khoom siv superconducting.
Ntawm cov ntaub ntawv superconducting, tsuas NBB tau muaj dua superconducting kev hloov pauv kub. Nyob rau tib lub sijhawm, Niobium buride yog cov khoom siv raw ntawm kub brazing khoom. Tom qab cov khoom brazing yog brazed nrog refractory hlau nbn, lub zog yog zoo heev lub zog ntawm lub weld.
