I-Niobium Nitride, i-gray ekhanyayo iphuzi kancinci, ukuxinana kwe-8.47g / cm3, indawo yokunyibilika yi-2300 ° C; ubunzima be-Mohs yi-8, i-microhardness yi-14.3GPa; inguqu yayo superconducting ebalulekileyo iqondo lobushushu 15.6K. I-insoluble kwi-hydrochloric acid, i-nitric acid, i-sulfuric acid; I-soluble kwisisombululo se-asidi esixubileyo se-hydrofluoric acid kunye ne-asidi ye-sulfuric Kwakhona iyanyibilika kwi-alkali eshushu okanye kwi-lye yoxinaniso ophezulu kwaye ikhupha i-ammonia.
Isetyenziswe njengesongezelelo se-carbide, inokuvelisa i-niobium ephezulu.
Inkonzo esinokubonelela ngayo
1) Ikhontrakthi esemthethweni inokusayinwa
2) Isivumelwano sokugcinwa kwemfihlo singasayinwa
3) Isiqinisekiso sokubuyiselwa kweentsuku ezisixhenxe
Okubaluleke ngakumbi: asikwazi ukubonelela ngemveliso kuphela, kodwa inkonzo yesisombululo seteknoloji!
Singabavelisi, umzi-mveliso wethu useShandong, kodwa sinokubonelela ngenkonzo enye yokuthenga!
T/T(telex transfer), Western Union, MoneyGram, BTC(bitcoin), njl.
≤25kg: kwiintsuku ezintathu zokusebenza emva kokuba intlawulo ifunyenwe. ＞25kg: iveki enye
Iyafumaneka, sinokubonelela ngeesampuli ezincinci zasimahla ngenjongo yokuvavanya umgangatho!
1kg ingxowa nganye fpr iisampulu, 25kg okanye 50kg igubu ngalinye, okanye njengoko ubufuna.
Gcina isikhongozeli sivalwe ngokuqinileyo kwindawo eyomileyo, epholileyo nengena umoya.
