Abstract

To achieve the object of providing a mixture for producing sinterable mouldings that allows high pressed densities to be obtained in a green compact, a mixture is proposed which comprises at least one metallic material and/or plastics material and at least one pressing aid, the pressing aid comprising about 0.5% to about 60% by weight, based on the total amount of the pressing aid, of at least one amide, and about 40% to about 99.5% by weight, based on the total amount of the pressing aid, of at least one carnauba wax.
