ABSTRACT:
A process for producing strip products which comprises forming an aqueous slurry of a suspension of metallic particles in a film forming cellulose derivative, depositing a quantity of the slurry onto a support surface, drying the slurry to form a self supporting flat product, removing the dried product from the support surface and roll compacting the same to produce a green strip. The green strip is supported on a moving surface as it travels to and enters a heater in which it is heated in an oxidising atmosphere to a temperature at which substantially all traces of the cellulose derivative are removed. The heated strip is fed while still on the moving support surface to and through a sinter furnace to form a coherent strip of the required composition.
