Abstract

A method for producing a thin openly porous metal film from a metal powder that can be sintered. The metal powder is suspended in a carrier fluid with a specific size distribution of particles, the suspension is applied to a supporting material in at least one thin film and dried, and the green layer thus formed is sintered. The thickness of the layer formed by suspension thus applied corresponds at least to the thickness (s) of the metal film to be produced after sintering, whereby (s) is at least three times the value of the diameter (D) of the powder particles, D=1-50 urn and the maximum thickness of the finished metal film is 500 &mgr;m.
