Ultrasonic Chemical Processing: Pyrometallurgical reduction of U/sub 3/O/ sub 8/ by molten magnesium in cadmium with ultrasonic excitation has effected greater than 99% reaction in four hours. Oxide-coated fissium pins were successfully fractured with low-power ultrasonic treatment at 1050 and 1200 deg C, consolidating the metal and yielding finely divided oxide flake. Ultrasonic Metal and Ceramic Powder Processing: A formulation of 38900 alumina containing 13.4 wt.% H/sub 2/O and 1 wt.% Superloid, which was too dry to be extruded, was extruded successfully with ultrasonic die activation. Ultrasonic extrusion of this composition represents more than two-fold reduction in the required amount of water. Simulated plate-type fuel elements, 0.060-in. thick and 24-in. deep, were successfully cast with standard ceramic formulations caused by the flow promotional effect of applied ultrasonic vibration. Ultrasonic mold activation resulted in the casting of slips with substantially increased solids content. Ultrasonic Instrumentation: Previous impedance measurements obtained by motional- loop, and elastic standing-wave-ratio methods for aqueous slurries of nickel and glass beads were confirmed. Experimental evidence showed that characteristics of various slurry concentrations can be determined in vessels of simple geometry without standing-wave variations influencing the results. (auth)
