Zone Melting by Electric Arc
- North American Aviation, Inc., Canoga Park, CA (United States). Atomics International Div.
An apparatus is described which uses a dc arc to produce a molten region for a zone-melting purification process. A specimen metal bar rests on a water-cooled hearth and serves as an anode. Metal in the liquid zone retains its continuity by virtue of surface tension and cohesion forces existing between it and the solidified pieces on each side. This adaptation of the arc furnace principle has the salient feature of low contamination. The data obtained indicate preferential migration of zirconium in thorium-zirconium alloys, with the best results indicating an end-to-end redistribution factor of about three after three passes. This investigation was carried out to determine prospects of fission-product removal from thorium-rich fuel materials.
