Abstract

Nb ₅Si ₃ intermetallic compound was directly synthesized via an electrodeoxidation process from molten CaCl ₂ electrolyte. The reaction mechanism was studied by performing a series of quenching investigations, which suggested that the formation of a series of sub oxides and compounds containing calcium and oxygen preceded the formation of Nb ₅Si ₃. While Nb ₂O ₅ was gradually reduced to its sub oxides, (Nb ₂O ₅/NbO ₂/NbO/Nb), SiO ₂, on the other hand, got directly reduced to silicon and reacted with Nb to form Nb ₅Si ₃.
