Bohloeki bo Phahameng Ferro Niobium In Stock
NIOBIUM - Sesebelisoa sa boqapi bo nang le bokhoni bo boholo ba bokamoso
Niobium ke tšepe e 'mala o moputsoa o bobebe e nang le ponahalo e tšoeu e benyang libakeng tse bentšitsoeng. E tšoauoa ka sebaka se phahameng sa ho qhibiliha sa 2,477 ° C le boima ba 8.58g/cm³. Niobium e ka etsoa habonolo, esita le ka mocheso o tlase. Niobium ke ductile mme e hlaha ka tantalum ka har'a ore ea tlhaho. Joalo ka tantalum, niobium e boetse e na le khanyetso e ikhethang ea lik'hemik'hale le oxidation.

Tlhaloso:
Karolo e ka sehloohong ea ferronobium ke motsoako oa tšepe oa niobium le tšepe. E boetse e na le litšila tse kang aluminium, silicon, carbon, sebabole le phosphorus. Ho ea ka litaba tsa niobium tsa alloy, e arotsoe ka FeNb50, FeNb60 le FeNb70. Alloy ea tšepe e hlahisoang ka ore ea niobium-tantalum e na le tantalum, e bitsoang niobium-tantalum iron. Li-alloys tsa Ferro-niobium le niobium-nickel li sebelisoa e le li-additives tsa niobium ho qhibilihisoa ha li-alloys tse thehiloeng ka tšepe le li-alloys tse thehiloeng ho nickel. Ho hlokahala hore ho be le khase e tlaase le litšila tse fokolang tse kotsi, tse kang Pb, Sb, Bi, Sn, As, joalo-joalo <2 × 10, kahoo e bitsoa "VQ" (boleng ba vacuum), joalo ka VQFeNb, VQNiNb, etc.
Kopo:
Ferroniobium e sebelisoa haholo-holo bakeng sa ho qhibilihisa mocheso o phahameng (o hanyetsanang le mocheso) motsoako, tšepe e sa hloekang le tšepe e matla e tlaase ea alloy. Niobium e etsa niobium carbide e tsitsitseng e nang le carbon ka tšepe e sa hloekang le tšepe e thibelang mocheso. E ka thibela kholo ea lijo-thollo ka mocheso o phahameng, ea ntlafatsa sebopeho sa tšepe, 'me ea ntlafatsa matla, boima le thepa ea tšepe ea tšepe.
