Sharaxaada
Niobium Carbide NbC,budada bunni khafiifka ah, oo leh nidaamka kiristaalo sodium chloride nooca cubic crystal, barta dhalaalaysa 3490°C, barta karkarinta 4300°C, cufnaanta 7.56g/cm3, waa mid aan ku milmin biyaha iyo aashitada inorganic, laakiin waxay ku milmi kartaa aashitada isku dhafka ah ee hydrofluoric acid iyo nitric acid waana la burburin karaa.Niobium Carbide kaliya looma isticmaali karo wax lagu daro si loo xakameeyo koritaanka miraha alloy si loo ganaaxo hadhuudhka karbide crystalline cemented ee soo saarista carbide sibidhka, laakiin sidoo kale waxay sameeyaan wejiga saddexaad ee kala firidhsan oo leh carbides kale marka laga reebo WC iyo Co, taas oo si weyn u hagaajin karta adkaanta kulaylka, caabbinta shoogga kulaylka, iska caabin cadaadis kulul iyo caabbinta oksaydhka ee karbidhida sibidhka.Iyada oo faa'iidooyinka hagaajinta qallafsanaanta iyo jabka adag ee daawaynta, waxaa loo isticmaali karaa in lagu diyaariyo qalabka carbide sibidhka leh ee waxqabadka goynta aad u fiican.Ka sokow, isagoo ah barta dhalaalaysa sare, engegnaanta sare iyo xasiloonida kiimikada, NbC sidoo kale waxaa loo isticmaalaa sida walxaha refractory heerkulka sare iyo alaabta daahan buufin ee warshadaha hawada.
gaarsiin
Niobium Carbide NbC iyo Tantalum Carbide TaC ee Western Minmetals (SC) Corporation waxaa lagu geyn karaa cabbirka budada 0.5-500 micron ama 5-400 mesh ama sida loo habeeyey, xirmo 25kg, 50kg oo bac ah oo leh durbaan bir ah oo dibadda ah.
