Claim 0:
1. A method of forming a near-net shape structure, the method comprising:
sintering a green structure exhibiting a green structure shape and comprising a stoichiometric metal oxide in a reducing atmosphere to form a structure comprising a non-stoichiometric metal oxide comprising at least one metal and less than a stoichiometric amount of oxygen; and
after sintering the green structure to form the structure comprising the non-stoichiometric metal oxide, electrochemically reducing the non-stoichiometric metal oxide in an electrochemical cell to form a near-net shape structure comprising the at least one metal and having less than about 1,500 ppm oxygen, wherein the near-net shape structure has a shape substantially corresponding to the green structure shape.
