Niobium nitride - guryaha
Cawl cirro leh oo midab huruud ah leh. Cufnaanta qaraabada 8.47I barta dhalaalida 2300 ℃; Kuleylka sameynta -237.8kj / mol; Mohs adkaanta 8, adkaanta micro 14.3GPA; Diidmada 200U. Cm. Kuleylka ku-meel-gaadhka ah ee heerkulka halista ahi waa 15.6 K. Laguma milmi karo aaladda hydrochloric acid, nitric acid iyo sulfuric acid; Lagu milmi karo hydrofluoric acid iyo sulfuric acid xal urursan, sidoo kale lagu milmi karo salka kuleylka ah ama heerka sare ee alkalinka, iyo sii deynta ammonia.
Sida carbide daro, niobium daahir sare sidoo kale waa la heli karaa. Marka lagu kululeeyo 500 ~ 800 ℃ hawo, niobium pentoxide waa la sameeyaa nitrogen-na waa la siidaayaa. Niobium nitride waxaa loo galiyay bir niobium oo faaruq ah. Niobium nitride iyo titanium carbide, zirconium carbide, vanadium carbide, tantalum oxide, iwm ayaa sameyn kara xal adag.
Caadi ahaan xeryahooda B-1. Qaab dhismeedka crystal sodium chloride. Heerkulka halista ah ee firfircoonida waa 17.3K. Qeybta sare ee birlabta waa 43T. Cufnaanta culus ee hadda jirta Jc, (4.2K, 20T) waa ilaa 2 × 106A / cm2. Xasiloonida kuleylka sare iyo xasilloonida kiimikada, shucaaca ka hortagga neerfayaasha, qalabka filimka khafiifka ah oo aad u wanaagsan. Isku darka argon iyo nitrogen waxaa lagu diyaariyey habka xarkaha. Waxaa loo isticmaalaa in lagu soo saaro aaladaha qalabka koombiyuutarka ku shaqeeya superconducting heer sare ah oo deggan iyo qalabka koronto.
