I-niobium nitride, grey elikhanyayo liphuzi kancane, ubuningi obuhlobene ngu-8.47g / cm3, iphuzu lokuncibilika lingu-2300 ° C; Ubulukhuni be-mohs bungu-8, i-microhardness ingu-14.3gpa; Izinga lokushisa elibucayi le-Superconducting Trances lise-15.6k. Insoluble ku-hydrochloric acid, nitric acid, sulfuric acid; Solula kwikhambi elihlanganisiwe le-acid le-hydrofluoric acid kanye ne-sulfuric acid futhi kuncibilika ku-alkali noma ephakeme kakhulu ngaphakathi kanye nokuhlushwa i-ammonia.
Isetshenziswa njengesengezo se-carbide esenziwe ngesiworeli, ingakhiqiza futhi i-niobium ehlanzekile ebuhlungu.
Insiza esingayinikeza
1) inkontileka ehlelekile ingasayinwa
2) Isivumelwano semfihlo singasayinwa
3) Isiqinisekiso Sezinsuku eziyisikhombisa
Okubaluleke kakhulu: Asinikezi kuphela umkhiqizo, kepha insizakalo yokhambi lobuchwepheshe!
Singabakhiqizi, ifektri yethu itholakala eShandong, kepha futhi singanikeza nensizakalo eyodwa yokuthenga!
I-T / T (TELEX TRRANCH), Union Western, MoneyGram, BTC (Bitcoin), njll.
≤25kg: kungakapheli izinsuku ezintathu zomsebenzi ngemuva kokuthola inkokhelo. > 25kg: isonto elilodwa
Kuyatholakala, singanikeza amasampula amancane wamahhala wenhloso yokuhlola yekhwalithi!
I-1kg ngesikhwama ngasinye se-FPR samasampula, i-25kg noma i-50kg ngesigubhu ngasinye, noma njengoba udinga.
Gcina isitsha esivalwe ngokuqinile endaweni eyomile, epholile futhi enomoya omuhle.
