Niobium Nitride, khafiif khafiif ah ayaa xoogaa huruud ah, cufnaanta qaraabada waa 8.47g / cm3, meesha dhalaalaysa waa 2300 ° C; Moohs adkaanta waa 8, microhardness-ka waa 14.3gpa; Heerkulka ka-hortagga guud ee is-weydaarsiga waa 15.6k. Aan ku dhexjiro hydrochloric acid, nitric acid, sulfuric acid; Isku-darka xalka aashitada ee aashitada ee hydrofluoric acid iyo sulfuric acid waxay sidoo kale ku milmaysaa alkali kulul ama qanjirada aad u sarreysa oo ay ka soo saarto ammonia.
Waxaa loo isticmaalaa sidii wax lagu daro xaraashka loo yaqaan 'Canebide'. Waxay kaloo soo saari kartaa niobium-ka sareeya.
Adeeg aan bixin karno
1) Qandaraaska rasmiga ah waa la saxeexi karaa
2) Heshiiska sirta ayaa la saxeexi karaa
3) Toddobo maalmood oo dammaanad celin ah
Ka sii muhiimsan: Waxaan bixin karnaa oo keliya wax soo saarka, laakiin adeegga xalka tikniyoolajiyadda!
Waxaan nahay soo-saare, warshadeena waxay ku taalaa Shandong, laakiin sidoo kale waxaan ku siin karnaa hal adeeg iska-iibsi oo adiga kuu ah!
T / T (Telex Beddelka), Western Union, Lacagta Mindinka, Lacagta, BTC (Bitcoin), iwm.
≤25kg: Saddex maalmood oo shaqo gudahood ka dib markii lacag bixinta la helay. > 25kg: hal toddobaad
Waxaa la heli karaa, waxaan ku siin karnaa muunado yar oo bilaash ah ujeedo qiimeyn tayo leh!
1kg halkii boorso muunad FPR ah, 25kg ama 50kg halkii durbaan, ama markii aad u baahan tahay.
Ku keydi weelka si adag u xir meel qalalan, qabow oo si fiican u hawo leh.
