Abstract
Official abstract text for this publication.
Thin, porous metal sheets and methods for forming them are presented to enable a variety of applications and devices. The thin, porous metal sheets are less than or equal to approximately 200 μm thick, have a porosity between 25% and 75% by volume, and have pores with an average diameter less than or equal to approximately 2 μm. The thin, porous metal sheets can be fabricated by preparing a slurry having between 10 and 50 wt % solvent and between 20 and 80 wt % powder of a metal precursor. The average particle size in the metal precursor powder should be between 100 nm and 5 μm.
First claim
Opening claim text (preview).
We claim: 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, m…
