Codsiyada Alaabta Niobium
Ilaalinta kulaylka iyo qalabka dhismaha ee duulista iyo warshadaha hawada, tuubooyinka elektiroonigga ah iyo qalabka kale ee faaruq koronto, walxaha superconducting, alloys kulaylka u adkaysta iyo karbides sibidhka, iwm.
Hordhac Walxaha Niobium
Waraaqahayaga niobium waa qaboojin duuban oo faaruq ah oo la jeexjeexay oo leh qiime dhimis lahaanshaha si loo hubiyo birta ku habboon. Xaraash kastaa waxa lagu maraa kormeer adag ee cabbirka, dhammaystirka dusha sare, iyo fidsanaanta.
Xaashiyaha Niobium waa birta ugu khafiifsan (cufnaanta 8.57 g/cc) waxayna leedahay heerkul dhalaal sare leh (2,468ºC). Hantidani waxay u oggolaanaysaa alwaaxyadeeda si ay u bixiyaan xalal dhismeed heerkul sarreeya: ka sarreeya 600ºC ee daawaha ku salaysan nikkel iyo sida ugu sarreeya 1,300ºC ee niobium ku salaysan.
Xaashida Niobium waxay leedahay astaamo jidheed iyo kiimiko oo la mid ah tan tantalum curiyaha. Waxay ka hortagtaa daxalka maadaama ay sameyso filim dielectric oxide ah. Birtu waxay ku bilaabataa inay si degdeg ah hawada ugu oksijiso 200ºC.
Hoos -264ºC, niobium waxay soo bandhigtaa sifooyin heer sare ah. Waxay qabataa cufnaanta sare ee koronto-la'aanta iska caabbinta, abuurista dhul birlab ah iyo xoogag soo saara codsiyo wax ku ool ah oo muhiim ah meelaha sida baarista caafimaadka, baarista agabka iyo gaadiidka.
