Ferro Niobium ifite ubwiza bwinshi (High Purity) iri mu bubiko
NIOBIUM – Ibikoresho by'udushya dufite ubushobozi bukomeye mu gihe kizaza
Niobium ni icyuma cy'umukara woroshye gifite ishusho y'umweru ugaragara ku buso busesuye. Kirangwa n'aho gishonga cyane cya 2,477°C n'ubucucike bwa 8.58g/cm³. Niobium ishobora gukorwa byoroshye, nubwo haba hari ubushyuhe buke. Niobium ni ductile kandi iboneka hamwe na tantalum mu mabuye karemano. Kimwe na tantalum, niobium inafite ubushobozi bwo kurwanya ubutabire n'ubushyuhe.

Ibisobanuro:
Igice cy'ingenzi cya ferroniobium ni aloyi y'icyuma ya niobium n'icyuma. Irimo kandi imyanda nka aluminiyumu, silikoni, karuboni, sulfur, na fosifore. Dukurikije ingano ya niobium muri aloyi, igabanyijemo FeNb50, FeNb60 na FeNb70. Aloyi y'icyuma ikorwa na niobium-tantalum ore irimo tantalum, yitwa niobium-tantalum iron. Aloyi za Ferro-niobium na niobium-nickel zikoreshwa nk'inyongera za niobium mu gushonga ikoresheje icyuma n'aloyi zishingiye kuri nickel. Isabwa kugira gazi nke n'imyanda nkeya, nka Pb, Sb, Bi, Sn, As, nibindi. <2×10, bityo yitwa "VQ" (ubwiza bw'imvange), nka VQFeNb, VQNiNb, nibindi.
Porogaramu:
Ferroniobium ikoreshwa cyane cyane mu gushongesha aloyi ishyushye cyane (irwanya ubushyuhe), icyuma kidashonga n'icyuma gifite imbaraga nkeya. Niobium ikora karubide ya niobium ihamye hamwe na karuboni mu cyuma kidashonga n'icyuma kidashonga. Ishobora kubuza gukura kw'ibinyampeke ku bushyuhe bwinshi, ikanatunganya imiterere y'icyuma, kandi ikanoza imbaraga, gukomera n'ubushobozi bwo gukurura icyuma.
