ʻO Niobium Nitride, ʻeleʻele iki ka hina hina, ʻo 8.47g/cm3 ka mea hoʻoheheʻe pili, ʻo 2300 ° C ka helu hoʻoheheʻe; ʻO ka paʻakikī Mohs he 8, ʻo ka microhardness he 14.3GPa; ʻO 15.6K kona wela hoʻololi superconducting. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka waika hydrochloric, nitric acid, sulfuric acid; hiki ke hoʻoheheʻe ʻia i loko o ka ʻakika koʻikoʻi o ka waika hydrofluoric a me ka ʻakika sulfuric Hiki ke hoʻoheheʻe ʻia i loko o ka alkali wela a i ʻole ka lye concentration kiʻekiʻe a hoʻopuka i ka amonia.
Hoʻohana ʻia e like me ka mea hoʻohui carbide cemented, hiki iā ia ke hana i ka niobium maʻemaʻe kiʻekiʻe.
ʻO ka lawelawe hiki iā mākou ke hāʻawi
1) Hiki ke hoʻopaʻa inoa ʻia ka ʻaelike maʻamau
2) Hiki ke pūlima ʻia ka ʻaelike hūnā
3) ʻEhiku lā hoʻihoʻi hōʻoia
ʻOi aku ka mea nui: hiki iā mākou ke hāʻawi i ka huahana wale nō, akā ʻo ka lawelawe ʻenehana hoʻonā!
He mea hana mākou, aia kā mākou hale hana ma Shandong, akā hiki iā mākou ke hāʻawi i kahi lawelawe kūʻai kūʻai hoʻokahi no ʻoe!
T/T (telex transfer), Western Union, MoneyGram, BTC (bitcoin), etc.
≤25kg: i loko o ʻekolu mau lā hana ma hope o ka loaʻa ʻana o ka uku. ＞25kg: hoʻokahi pule
Loaʻa, hiki iā mākou ke hāʻawi i nā laʻana liʻiliʻi liʻiliʻi no ke kumu loiloi maikaʻi!
1kg no ka ʻeke fpr samples, 25kg a i ʻole 50kg no ka pahu, a i ʻole e like me kou makemake.
E mālama i ka pahu i paʻa paʻa i kahi maloʻo, anuanu a maikaʻi hoʻi.
