Abstract:

The literature review of tantalum and anodic oxidation references was essentially completed. Chemical methods required for analysis of the manganese dioxide electrolyte were developed. Some development was done on metallographic methods for examining samples. Particle shape was ound to have little effect on anode wet cell properties, b t particle size distribution and sintering tec niques were found to exercise c n iderable control over anode quality. Compacting studies were made on powders with other variables than particle size distribution held constant. A ethod of determining surface wettability and restoring wettability by the ormation electrolyte as found. Processing studies progressed to a point where foam with reproducible characteristics can be made. Electrical characteristics were measured relative to several variables in the foam process. Author
