I-Niobium Nitride, okumpunga okukhanyayo kuphuzi kancane, ukuminyana okuhlobene kungu-8.47g/cm3, indawo yokuncibilika ingu-2300 ° C; ubulukhuni be-Mohs bungu-8, ubulukhuni obuncane bungu-14.3GPa; I-superconducting transition yayo izinga lokushisa elibalulekile lingu-15.6K. I-insoluble ku-hydrochloric acid, i-nitric acid, i-sulfuric acid; I-soluble ku-concentrated acid solution ye-hydrofluoric acid ne-sulfuric acid Iphinde inyibilike ku-alkali eshisayo noma ku-lye yokugxila okuphezulu futhi ikhiphe i-ammonia.
Isetshenziswa njengesengezo se-carbide esine-cemented, ingaphinda ikhiqize i-niobium ehlanzekile kakhulu.
Isevisi esingayinikeza
1) Inkontileka esemthethweni ingasayinwa
2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa
3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa
Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
Singabakhiqizi, imboni yethu itholakala eShandong, kodwa futhi singakunikeza insizakalo eyodwa yokuthenga!
T/T(i-telex transfer), Western Union, MoneyGram, BTC(bitcoin), njll.
≤25kg: zingakapheli izinsuku ezintathu zokusebenza ngemuva kokutholwa kwenkokhelo. ＞25kg: isonto elilodwa
Kuyatholakala, singanikeza amasampula amancane mahhala ngenjongo yokuhlola ikhwalithi!
1kg isikhwama ngasinye fpr amasampula, 25kg noma 50kg isigubhu ngasinye, noma njengoba ubufuna.
Gcina isitsha sivalwe ngokuqinile endaweni eyomile, epholile futhi enomoya omuhle.
