<p>A process for producing a sintered body, especially a consumable anode, from a metal powder, characterised in that during or prior to sintering of an agglomerated or compacted body of a metal powder, consisting of a single metal, a metal alloy or a mixture of two or more metals and/or alloys, an activating film is present on the surface of some or all of the powder particles, whereby sintering of the particles is activated, and during subsequent stages of the process the film is at least partially destroyed and removed. The activating film is formed by treating the powder with an activator such as sulphur, selenium, tellurium, or a halogen, or a compound thereof, which reacts with the metal to form the film.</p> |
