Nadiifinta Sare ee Ferro Niobium In Stock
NIOBIUM – Qalab loogu talagalay hal-abuurnimada leh mustaqbal wanaagsan
Niobium waa bir cawlan khafiif ah oo leh muuqaal cad oo dhalaalaysa oo ku yaal sagxadaha la safeeyey.Waxaa lagu gartaa meel sare oo dhalaalaysa oo ah 2,477°C iyo cufnaanta 8.58g/cm³.Niobium si fudud ayaa loo samayn karaa, xitaa heerkulka hooseeya.Niobium waa ductile waxayna ku dhacdaa tantalum ee macdanta dabiiciga ah.Sida tantalum, niobium sidoo kale waxay leedahay caabbinta kiimikada iyo oksaydhka.

Sharaxaada：
Qaybta ugu muhiimsan ee ferroniobium waa birta daawaha ee niobium iyo birta.Waxa kale oo ku jira wasakhda sida aluminium, silikon, kaarboon, baaruud, iyo fosfooraska.Marka loo eego nuxurka niobium ee daawaha, waxa loo qaybiyaa FeNb50, FeNb60 iyo FeNb70.Daawaha birta ee lagu soo saaro niobium-tantalum ore waxa ku jira tantalum, loo yaqaan niobium-tantalum iron.Ferro-niobium iyo niobium-nickel alloys waxaa loo isticmaalaa sida niobium-ka lagu daro dhalada faakuumka ee alloys-ku-saleysan birta iyo nikkel-ku-saleysan.Waxaa loo baahan yahay in uu yeesho gaas yar iyo wasakhda waxyeelada leh oo hooseeya, sida Pb, Sb, Bi, Sn, As, iwm. <2×10, sidaas darteed waxaa loo yaqaan "VQ" (Vacuum quality), sida VQFeNb, VQNiNb. iwm.
Codsiga：
Ferroniobium waxaa inta badan loo isticmaalaa dhalaalinta heerkulka sare (kulka u adkaysta) daawaha, birta aan lahayn iyo xoogga sare ee birta alloy hoose.Niobium waxay samaysaa niobium carbide xasiloon oo leh kaarboon ku jira birta aan fiicnayn iyo birta u adkaysata kulaylka.Waxay ka hortagi kartaa korriinka hadhuudhka heerkulka sare, hagaajinta qaabka birta, waxayna wanaajisaa xoogga, adkaanta iyo guryaha gurguurta ee birta
