spherical kiʻekiʻe maʻemaʻe niobium carbide pauka
Hōʻike huahana
ʻO ka pauka Niobium carbideHe ʻano mea ʻano mea ʻole me ka waiwai hoʻohana koʻikoʻi.Hoʻokumu nui ʻia ia me ka niobium a me ke kalapona, a loaʻa iā ia nā waiwai kino, kemika a me ka mechanical.ʻO nā kaʻina hana nui o ka hana ʻana i ka pauka niobium carbide me ke ʻano hoʻemi carbothermal a me ke ʻano electrolysis paʻakai hoʻoheheʻe.I waena o lākou, ʻo ke ʻano hoʻemi carbothermal ka mea maʻamau i hoʻohana ʻia, ʻo ke kumumanaʻo e hōʻemi i ka niobium oxide a i ʻole niobium alloy me ke kalapona i ke kiʻekiʻe wela e loaʻa ai ka pauka niobium carbide.ʻO ke ʻano o ka paʻakai hoʻoheheʻe electrolysis ʻo ia ka hoʻohana ʻana i ka hui ʻana o ka paʻakai niobium a me ka paʻakai kalapona i ka electrolysis ma ke kiʻekiʻe wela, i hoʻemi ʻia ka niobium ion i ka niobium carbide ma ka cathode.
Hoʻohana nui ʻia ka pauka Niobium carbide i nā kula he nui, e like me ka uila, aerospace, mīkini, metallurgy a pēlā aku.Ma ke kahua o ka uila, hiki ke hoʻohana ʻia ka niobium carbide e hana i nā mea superconducting kiʻekiʻe a me nā mea uila ma muli o kona kiʻekiʻe koʻikoʻi koʻikoʻi a me ka pale radiation.Ma ke kahua o ka aerospace, ua loaʻa i ka niobium carbide alloy nā mea maikaʻi o ka ikaika kiʻekiʻe, ke kaumaha māmā a me ka pale ʻana i ka corrosion, a he mea nui ia i ka hana ʻana i nā mīkini mokulele a me nā ʻāpana rocket.

Pūnaehana hoʻomalu maikaʻi
He ʻōnaehana koʻikoʻi ko Huarui.Ho'āʻo mua mākou i kā mākou huahana ma hope o ka hoʻopau ʻana i kā mākou hana, a hoʻāʻo hou mākou ma mua o kēlā me kēia lawe ʻana, ʻo ia hoʻi ka laʻana.A inā makemake ʻoe, makemake mākou e ʻae i ka ʻaoʻao ʻekolu e hoʻāʻo.ʻOiaʻiʻo inā makemake ʻoe, hiki iā mākou ke hāʻawi i kahi laʻana iā ʻoe e hoʻāʻo.
Hoʻopaʻa ʻia kā mākou huahana huahana e Sichuan Metallurgical Institute a me Guangzhou Institute of Metal Research.Hiki i ka hui lōʻihi me lākou ke mālama i ka manawa hoʻāʻo nui no nā mea kūʻai aku.
