The dissolution of uranium slugs in molten cadmium was conducted in the high-temperature inert atmosphere ultrasonic treatment furnace. Analysis of the cadmium melt disclosed equilibrium concentrations (2.27 wt. %) of uranium present after 2-hour ultrasonic treatment at 525 deg C in contrast to 0.01 wt.% uranium for a 2-hour non-ultrasonic control. In metal and ceramic powder processing, ultrasonic activation of the extrusion die resulted in substantial improvements in the extrusion process. Experiments with duplicate batches of the same alumina formulation demonstrate that under ultrasonic treatment extrusion is readily effected near the maximum travel rate of the piston at a pre-set press load, whereas without ultrasonics no extrusion is obtained. For certain water concentrations the load requiremert can be reduced to 1/8th of the force necessary without ultrasonics. Flow rate of alumina and clay slips through a 0.050-in. ID orifice under ultrasonic treatment increased as much as 300% over the flow rate without ultrasonios. Thus, ultrasonic flow promotion appears feasible for casting pin- and plate-type elements.
