Abstract:
1. A method of fabricating a thin, porous metal sheet, the method characterized by the steps of: Preparing a slurry comprising between 10 and 50 wt % solvent and between 20 and 80 wt % non-metallic powder of a metal oxide, metal hydride or metalorganic, the non-metallic powder comprising average particle sizes from 100 nm to 5 μm; Casting the slurry into a green body having a thickness between 10 and 200 μm; Firing the green body thereby converting the metal oxide, metal hydride or metalorganic into a metallic state and yielding a fired body; and Sintering, annealing or flattening the fired body to yield the thin, porous metal sheet having a metallic backbone of networked pore structures in three dimensions with a porosity between 25% and 75% by volume, and with an average pore diameter less than or equal to 2 μm.
