Production of Nb-Zr alloy by aluminothermic reduction-electron beam refining 1st Report. Fundamental Study of Aluminothermic Reduction of Niobium Oxide and Zirconium Oxide.

Shigen-to-Sozai, 1991
Aluminothermic reduction of Nb2O5 or Nb2O5 /ZrO2 mixture followed by the electron beam melting to produce Nb-1% Zr alloy has been investigated. On the aluminothermic reduction of both Nb2O5 and Nb2O5/ZrO2 mixture, 70g and 210g batch tests were carried out to estimate possibility of the production of Nb-Zralloys.Good seperation of metal from slag was ...
