Abstract:
A method for forming a self-supporting body, comprising:providing at least one solid oxidant-containing material;providing at least one first vapor-phase parent metal;contacting at least a portion of said at least one solid oxidant-containing material with said at least one first vapor-phase parent metal;permitting said at least one first vapor-phase parent metal and said portion of said at least one solid oxidant-containing material to form at least one first reaction product on said portion of said at least one solid oxidant-containing material;subsequent to said permitting of said at least one first reaction product to form, providing at least one second vapor-phase parent metal having a different chemical composition from said at least one first vapor-phase parent metal;contacting at least a portion of said at least one first reaction product with said at least one second vapor phase parent metal; andreacting said at least one second vapor-phase parent metal with said at least one reaction product, thereby forming at least one second reaction product having a different chemical composition from said first reaction product.
