Abstract

Green mouldings of metal powder and/or ceramic powder are obtained by filling a cooled mould with a mixture of the metal and/or ceramic powder containing 30 to 55% of tertiary butanol as binder. The mixture is at a temperature above the melting point of tertiary butanol, and is cooled in the mould to a temperature below the melting point of methanol. The use of tertiary butanol as binder leads to easy mould release, and since it can be removed from the green moulding at low pressure and relatively low temperature, without decomposition, it is reusable, avoiding the problems of the known decomposable organic binders, and the corrosion resulting from aqueous binders.
