Descriptio Productorum
Ferrotungstenum ex wolframite per reductionem carbonis in furno electrico paratur. Praecipue ut additivum elementi mixturae pro chalybe mixto tungstenum continente (velut chalybe celerrimo) adhibetur. Tria genera ferrotungsteni in Sinis producuntur, inter quae w701, W702 et w65, cum contento tungsteni circiter 65 ~ 70%. Propter altum punctum liquefactionis, ex liquido effluere non potest, ita per methodum coagulationis vel methodum extractionis ferri producitur.
Wolframii contentum: 70%-80%
Aspectus: Metallum argenteum-cinereum
Materia: Mn, Si, C, S, Cu, P

Ferroniobium Altae Puritatis In Promptu
NIOBIUM – Materia innovationum magno potentiali futurae. Niobium est metallum griseum pallidum, aspectu albo nitido in superficiebus politis. Notum est puncto liquefactionis alto 2477°C et densitate 8.58g/cm³. Niobium facile formari potest, etiam temperaturis humilibus. Niobium ductile est et cum tantalo in minerali naturali invenitur. Sicut tantalum, niobium etiam egregiam resistentiam chemicam et oxidationis praebet. Compositio chemica % Marca FeNb70 FeNb60-A FeNb60-B F...
