Tantalum carbide pauka, TaC

Aloha, e hele mai e nīnau i kā mākou huahana!

Tantalum carbide pauka, TaC

ʻO 1.44 ka nui o ke kaulike, ʻo 3730-3830 ° C ke kiko hoʻoheheʻe, ʻo 8.3 × 10-6 ka hoʻonui ʻana o ka thermal, 291GPa ke aniani uila, ʻo 0.22j / cm ka laulā o S conductivity.
Nā hiʻohiʻona a me nā hoʻohana
ʻO ke kūpaʻa kemika maikaʻi, ʻaʻole hiki ke hoʻohana ʻia i nā waikawa. Ka mana antioxidant ikaika. Hoʻohui pinepine ʻia ʻo TaC mai ka tantalum pentoxide a me ke kalapona ʻeleʻele i kahi inert a hoʻoliʻiliʻi paha i ka lewa e hana i kahi pauka keleawe.

Tanmlum carbide
ʻO ke kumulāʻau kemika ʻo TaC, ka latika cubic centered-face.
hāmeʻa
ʻO 1.44 ka nui o ke kaulike, ʻo 3730-3830 ° C ke kiko hoʻoheheʻe, ʻo 8.3 × 10-6 ka hoʻonui ʻana o ka thermal, ʻo 291GPa ke kaulike, ʻo ka coefficient o ka conductivity thermal he 0.22j / cm · S · C.
Nā hiʻohiʻona a me nā hoʻohana
ʻO ke kūpaʻa kemika maikaʻi, ʻaʻole hiki ke hoʻohana ʻia i nā waikawa. Ka mana antioxidant ikaika. Hoʻohui pinepine ʻia ʻo TaC mai ka tantalum pentoxide a me ke kalapona ʻeleʻele i kahi inert a hoʻoliʻiliʻi paha i ka lewa e hana i kahi pauka keleawe. ʻO nā huahana me ke kiʻekiʻena kiʻekiʻe a me ka luster metallic hiki ke hana ʻia e ke kahe ʻana i ka sinter wela. Hoʻohana ʻia ma ke ʻano he mea hoʻopili i nā pono aerospace a me nā mea paʻa paʻa.
Tantalum carbide
Ke ʻano o ka
ʻO ka paukū ʻeleʻele metallic cubic crystalline ka paukū, no ka ʻōnaehana sodium chloride cubic crystal. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, ʻaʻole hiki ke hoʻoheheʻe ʻia i nā waikomo inorganic, hiki ke hoʻoheheʻe ʻia i nā waikawa i hui ʻia o hydrofluoric a me nā waikawa nitric a hoʻonā ʻia i ka palaho. ʻO ke kūpaʻa kūpaʻa ikaika, maʻalahi e fuse a decomposed e ka potassium pyrosulfate. Nui ka uila uila, loaʻa iā 30 Ω kūʻē i ka mahana wela, nā waiwai superconducting.
hoʻohana
Hoʻohana ʻia i ka metallurgy paukū, nā mea hana ʻoki, nā pālolo maikaʻi, ka waiho ʻana o ka mahu kemika, nā mea hana paʻa paʻa paʻa, nā pono hana, nā palakō a kau i nā mea hoʻohui kūpale kūpale, hoʻonui i ka paʻakikī o ke kinikini. Hōʻike ke kino sintered o tantalum carbide i ke kala gula a hiki ke hoʻohana ʻia i mea kāhiko no nā wati. Hoʻohana pū ʻia ʻo ka Tantalum carbide sinter ulu laha i mea e kāohi ai i ka ulu ʻana o ka palaoa, me ka nui o 14.3g / cm3.
