Direct and low energy electrolytic co-reduction of mixed oxides to zirconium-based multi-phase hydrogen storage alloys in molten salts

Solid oxide membrane-assisted controllable electrolytic fabrication of metal carbides in molten salt

“…The electrodeoxidation-generated O 2À ions could also react with Ca 2+ ions and ZrO 2 to form Ca-Zr-O compounds during the electrodeoxidation process. 24,31 Aer being electrodeoxidized at 1000 C and 4.0 V for 6 h, pure ZrC (PDF# 35-0784) has been produced from the ZrO 2 /C precursors, as shown in Fig. 6a and b), indicating that the reaction, i.e., ZrO 2 + 0.15Ca 2+ + 0.6e À + 0.15C / Ca 0.15 Zr 0.85 O 1.85 + 0.15ZrC + 0.15O 2À occurred in the reaction area.…”

Synthesis of niobium aluminides by electro-deoxidation of oxides

“…This technique has been used to produce many metals and their alloys from their oxide precursors and the process has been modelled [37]. These alloys include Nb-Ti and Nb-Sn [24], Ti-Mo [28], Ti-Ni [29], Ti-W [32], Fe-Ti [33], Al-Sc [34], Ce-Ni [35] and Zr alloys [36]. As none of the existing methods for the production of aluminides seem ideal, this paper describes the application of electro-deoxidation to the synthesis of aluminides.…”

In-situ synthesis of MoSi2 coating on molybdenum substrate by electro-deoxidation of a SiO2 layer in molten salt

“…So far, most of the published works using the electrodeoxidation method have been focused on the fabrication of numerous metals and alloys powders, such as Ti [12], Cr [13], Ta [14], Si [15], Ti x Si y intermetallic compounds [16], TbFe 2 [17], AB 5 -type [18][19][20] and AB 2 -type [21] Hydrogen storage alloys, directly from their metal oxides. Meanwhile, functional coatings prepared by the electro-deoxidation method have also been demonstrated [22].…”
