Abstract
A method of: providing an emulsion having a zinc powder and a liquid phase; drying the emulsion to form a sponge; sintering the sponge in an inert atmosphere to form a sintered sponge; heating the sintered sponge in an oxidizing atmosphere to form an oxidized sponge having zinc oxide on the surface of the oxidized sponge; and heating the oxidized sponge in an inert atmosphere at above the melting point of the zinc. A method of: providing an emulsion comprising a zinc powder and a liquid phase; placing the emulsion into a mold, wherein the emulsion is in contact with a metal substrate; and drying the emulsion to form a sponge.
