This Cooperative Research and Development Agreement (CRADA) has been a three-year collaboration among the Y-12 Plant Development Division, Blasch Precision Ceramics, Inc., and Surface Alloys, Inc. The purpose of the CRADA was to evaluate the production of a totally new crucible that would be noncarbon and that could perform like graphite. The effort required materials fabricated into a workable crucible. The goal was to produce a crucible that could be induction heated and allow melting of reactive metals without appreciable carbon contamination. The US Department of Energy programs involving casting uranium and its alloys have long been concerned with reducing deleterious carbon pickup that results from the use of graphite crucibles. Therefore, the results of this CRADA provide an alternative that can eliminate carbon pickup from the graphite crucible
