ʻO Ferro Niobium maʻemaʻe kiʻekiʻe ma ka waihona
NIOBIUM - He mea waiwai no nā mea hou me ka mana nui e hiki mai ana
ʻO ka Niobium kahi metala hina hina me ke keʻokeʻo keʻokeʻo ma nā ʻaoʻao poni. Hōʻike ʻia ia e kahi helu heheʻe kiʻekiʻe o 2,477°C a me kahi mānoanoa o 8.58g/cm³. Hiki ke hana maʻalahi ka Niobium, ʻoiai ma nā mahana haʻahaʻa. ʻO ka Niobium he ductile a loaʻa me ka tantalum i loko o kahi ʻeleʻele maoli. E like me ka tantalum, hōʻike pū ʻia ka niobium i nā kemika koʻikoʻi a me ke kūpaʻa ʻana.

wehewehe：
ʻO ka mea nui o ka ferroniobium he hao hao o niobium a me ka hao. Loaʻa iā ia nā mea haumia e like me ka aluminika, ke silika, ke kalapona, ka sulfur, a me ka phosphorus. Wahi a ka niobium maʻiʻo o ka alloy, ua māhele ʻia i FeNb50, FeNb60 a me FeNb70. ʻO ka hao hao i hanaʻia me ka niobium-tantalum ore he tantalum, i kapaʻia he hao niobium-tantalum. Hoʻohana ʻia nā ferro-niobium a me ka niobium-nickel alloys e like me nā mea hoʻohui niobium i ka hoʻoheheʻe ʻana o nā mea hao a me nā nickel-based alloys. Pono ka loaʻa ʻana o ke kinoea haʻahaʻa a me nā haumia ʻino haʻahaʻa, e like me Pb, Sb, Bi, Sn, As, etc. <2×10, no laila ua kapa ʻia ʻo "VQ" (vacuum quality), e like me VQFeNb, VQNiNb, etc.
Palapala noi：
Hoʻohana nui ʻia ʻo Ferroniobium no ka hoʻoheheʻe ʻana i ke kiʻekiʻe kiʻekiʻe (heat resistant) alloy, stainless steel a me ka ikaika kiʻekiʻe. Hoʻokumu ʻo Niobium i ka niobium carbide paʻa me ke kalapona i ke kila kila a me ke kila wela. Hiki iā ia ke pale i ka ulu ʻana o ka palaoa i ka wela kiʻekiʻe, hoʻomaʻemaʻe i ke ʻano o ke kila, a hoʻomaikaʻi i ka ikaika, paʻakikī a me nā mea kolo o ke kila.
