Alta Puritas Ferro Niobium In Stock
NIOBIUM – Materia rerum novarum magna cum potentia futurae
Niobium est metallum glaucum cum candida specie in superficiebus politis.Notatur per altam liquefactionem punctum 2,477°C et densitatem 8.58g/cm³.Niobium facile formari potest, etiam humilis temperaturis.Niobium ductile est et fit cum tantalo in chalcitide naturali.Sicut tantalum, niobium etiam chemicae et oxidationis praestantissimae lineamenta resistentia.

Descriptio.
Praecipuum ferroniobium est mixtura ferrea niobium et ferri.Habet etiam immunditiam, ut aluminium, pii, carbonem, sulphur, phosphorum.Secundum niobium stannum, dividitur in FeNb50, FeNb60 et FeNb70.Mixtura ferrea producta cum ore niobium Tantalum continet tantalum, quod ferrum vocatur niobium Tantalum.Ferro-niobium et admixtiones niobium-nickel adhibentur ut Niobium additiva in vacuo excoquunt admixtiones ferreas substructio et admixtiones nickel fundatae.Oportuit habere contentum humilem et gravem immunditiam noxiam, ut Pb, Sb, Bi, Sn, As, etc. <2×10, sic appellatur "VQ" (quale vacuum), ut VQFeNb, VQNiNb; etc.
Applicationem.
Ferroniobium maxime adhibitum est ad ustionem caliditatis (caloris resistentis) mixturae, chalybis immaculatae et alte viribus demissis ferro mixturae.Niobium firmum niobium carbidam format cum carbone in ferro immaculato et ferro calori resistente.Frumentum incrementum caliditas impedire potest, structuram ferri expolire, et vires, duritias et proprietates ferri emendare.
