Containment of molten uranium alloys in powder metallurgical tungsten containers

Recently, in our laboratory, a necessity to contain molten uranium alloys such as URe2, UP, U-Nb etc., at temperatures of 2500 K arose. A systematic investigation of the compatibility of these alloys with tantalum and tungsten resulted in established that hot-swaged tungsten is a suitable container material. We have developed and experimentally demonstrated the less expensive powder metallurgical tungsten containers of 98% + theoretical density as alternatives. (orig.)
