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.

Production of flat products

A process for producing flat products from gas atomised particulate material comprises the steps of forming a relatively smooth castable slurry comprising a suspension of such particulate material in a solution of film-forming binder material, depositing a coating of the slurry onto a substrate or support surface and drying the coating to form a flexible flat product. The dried flat product may be bonded onto the substrate or support surface by the drying process or, alternatively, may be removed therefrom and roll-bonded to a suitable substrate for subsequent compaction and sintering.

Production of flat products from particulate material

A process for producing flat products from particulate material comprises the steps of forming relatively smooth, castable slurry comprising a suspension of particulate material in an aqueous solution, a film-forming binder material and a dispersion of a particulate synthetic resin in an aqueous solution, depositing a coating of this slurry onto a support surface and, heating the deposited coating to a temperature at which a component of the synthetic resin volatilises. The coating may be removed from the support surface as a flat product either before or after heating to volatilize a component of the synthetic resin.
