Abstract: A method of producing a substrate having a particulate coating of high surface area to mass ratio, said method comprising in sequence the steps of: I. disposing particles between a substrate and an intermediate body wherein the particles are harder than the substrate; and the intermediate body is softer than the particles but is harder than the substrate; II. compressing the substrate and intermediate body, with particles therebetween whereby the intermediate body pushes the particles into the substrate; and III. removing the intermediate body from the particles leaving them embedded in the substrate. The coating substrates produced by the process of the present invention find utility as catalytic devices to accelerate or retard chemical reactions, as getter devices to sorb residual gases in closed vessels such as electronic tubes, and with further processing as capacitors.
