Abstract
A method of forming an alloy includes disposing a first metal oxide and a second metal oxide in a molten salt. The molten salt is in contact with a working electrode and a counter electrode. An electrical potential is applied between the counter electrode and the working electrode to co-reduce the first metal oxide and the second metal oxide to form a first metal and a second metal, respectively.
Claims20
A method of forming an alloy, the method comprising:
- disposing a first metal oxide comprising cobalt oxide and a second metal oxide comprising nickel oxide in a molten salt, the molten salt in contact with a working electrode comprising nickel and a counter electrode;
- and
- applying an electrical potential between the counter electrode and the working electrode to co-reduce the first metal oxide and the second metal oxide to form a cobalt-nickel alloy.
A method of forming an alloy, the method comprising:
- disposing a first metal oxide and a second metal oxide in a molten salt, the molten salt in contact with a working electrode and a counter electrode, the working electrode comprising a metal selected from the group consisting of iron, nickel, cobalt, and combinations thereof;
- and
- applying an electrical potential between the counter electrode and the working electrode to co-reduce the first metal oxide and the second metal oxide to form a nickel-rich alloy of the first metal and the second metal.
A method of reducing metal oxides, the method comprising:
- providing an electrochemical cell comprising a working electrode, a counter electrode comprising a platinum-group metal, and a molten salt in contact with the working electrode and the counter electrode;
- disposing a material comprising at least two metal oxides in contact with the molten salt and the working electrode, one of the at least two metal oxides comprising nickel oxide;
- and
- providing an electric current between the counter electrode and the working electrode to reduce the at least two metal oxides to form an alloy comprising at least two metals formed by reduction, the alloy comprising a nickel-cobalt alloy, a samarium-cobalt alloy, or an iron-cobalt-nickel alloy.
