Binary Mixtures of Ultrafine Metal Powders.
II. Rolling of Ultrafine Powders into Porous Sheets

Abstract

The paper examines the possibility of producing porous sheets by rolling binary mixtures of ultrafine powders of nickel, copper, and cobalt. The effect of the rolling rate on the thickness and porosity of sheets and on the specific surface area of powders after rolling is studied. The best rollability is shown by nickel and copper powders and by powders produced from mechanical mixtures of formates.
