Niobium Nitride, imvi yopepuka ndi chikaso pang'ono, kachulukidwe kakuti ndi 8.47G / CM3, malo osungunuka ndi 2300 ° C; Kulimbana kwa Mohas ndi 8, microurdine ndi 14.3gpa; Kusintha kwake kwapamwamba kwa kutentha kovuta ndi 15.6k. Insuluble mu hydrochloric acid, nitric acid, sulfuric acid; Subleble omwe ali mu ydrofluoric acid ndi sulfuric acid amasungunuka mu madzi otentha alkali kapena yuni yayikulu kwambiri ndi emits Amonia.
Kugwiritsidwa ntchito ngati chowonjezera cha carbidide, chimathanso kupanga niobium kwambiri.
Ntchito Titha Kupereka
1) Contrated mgwirizano wovomerezeka akhoza kusankhidwa
2) Mgwirizano wachinsinsi ungasainidwe
3) Masiku asanu ndi awiri obweza ngongole
Chofunika kwambiri: Sitingangopereka malonda okha, koma njira yaukadaulo yaukadaulo!
Ndife opanga, fakitale yathu ili ku Shandong, koma titha kuperekanso munthu kuti asiye kugula kwa inu!
T / T (Tchalitchi), Western Union, Ngongole, BTC (Bitcoin), etc.
≤25kg: mkati mwa masiku atatu ogwira ntchito atalandira. > 25kg: sabata imodzi
Kupezeka, titha kupereka zitsanzo zazing'ono zaulere za cholinga chabwino!
1kg pa Thumba la FPRS zitsanzo, 25kg kapena 50kg pa ngoma pa Drum, kapena momwe mukufunira.
Sungani chidebe chomwe chatsekeka mwamphamvu pamalo owuma, ozizira komanso ozizira.
