Ferro Niobium Parakore Teitei Kei roto i te Toa
NIOBIUM – He rauemi mō ngā auahatanga me te pūmanawa nui ā muri ake nei
He konganuku hina mārama te niobium, he mā kanapa te āhua i runga i ngā mata kua orohia. Ko tōna ira rewa teitei ko te 2,477°C me te mātotoru o te 8.58g/cm³. Ka taea te hanga ngāwari i te niobium, ahakoa i ngā pāmahana iti. He ngāwari te niobium, ā, ka kitea tahi me te tantalum i roto i te konganuku taiao. Pērā i te tantalum, he tino ātete ki ngā matū me te waikura te niobium.

Whakaahuatanga：
Ko te wāhanga matua o te ferroniobium he koranu rino o te niobium me te rino. Kei roto hoki ngā poke pēnei i te konumohe, te silicon, te waro, te whanariki, me te phosphorus. E ai ki te nui o te niobium i roto i te koranu, ka wehea ki te FeNb50, FeNb60 me te FeNb70. Kei roto i te koranu rino i hangaia ki te konganuku niobium-tantalum te tantalum, e kiia nei ko te rino niobium-tantalum. Ka whakamahia ngā koranu Ferro-niobium me te niobium-nickel hei tāpiri niobium i roto i te whakarewa korehau o ngā koranu rino me ngā koranu nickel. Me iti te nui o te hau me te iti o ngā poke kino, pēnei i te Pb, Sb, Bi, Sn, As, me ētahi atu. <2×10, nō reira ka kiia ko "VQ" (kounga korehau), pēnei i te VQFeNb, VQNiNb, me ētahi atu.
Tono：
Ko te Ferroniobium te mea e whakamahia nuitia ana mō te whakarewa i te koranu pāmahana teitei (ātete wera), te maitai kore waikura me te maitai koranu iti kaha teitei. Ka hangaia e te Niobium te niobium carbide pumau me te waro i roto i te maitai kore waikura me te maitai ātete wera. Ka taea e ia te aukati i te tipu o te witi i te pāmahana teitei, te whakapai ake i te hanganga o te maitai, me te whakapai ake i te kaha, te pakari me ngā āhuatanga ngoki o te maitai.
