Using gelatin-stabilized kerosene-in-water emulsions as a simulant system. further experimental work with continuous-flow annular standing-wave treatment vessels resulted in agglomeration of a standardized emulsion. Consideration is now being given to the use of two annular treatment vessels operating in series. The tantalum crucible was incorporated into a high- temperature controlledatmosphere ultrasonic-treatment funnace designed for the study of ultrasonic pyrometallurgical processes. These include promotion of phase equilibrium in the extraction of plutonium from molten uranium. increase in rate of dissolution of fissium in molten cadmium. and break up of oxide shells on fuel pins. Investigation of anion-exchange resins in ultrasonic-colunm operation was continued with further evidence of enhanced exchange rates. Exploratory tests with very dilute solutions to study the mechanism of ultrasonic diffusion through liquid films were initiated. By application of ultrasonic energy. the increases in flow rate of both stainless steel and ceramic slips through narrow orifices have been observed. Implications in slip casting of fuel-element plates as pins of narrow cross section are discussed. Evaluation of specimens on the basis of density and green strength will be used to assess the effect of ultrasonics applied during the casting process. Preliminary extrusion tests were made with alumina using ammonium alginate and water as plasticizer. When ultrasonic energy was applied to the die. there was an increase in the extrusion rate and a concomitant reduction in the extrusion load. It was also found possible to extrude at a reduced water content. (For preceding period see NYO- 2569.) (auth)
