Evaluation procedures for tantalum wire and powder and test procedures for in-process inspection of partially processed anodes have been generated. The study of temporary binders has been completed and work on anode pressing is almost finished. Dehydration studies were ended except for life test in the first quarter. Two-thousand hour life showed no major differences attributable to moisture content. The Second Pilot Run was completed in March but final yield data are not all in. It appears that the final yield will show an improvement of about 40 over the First Pilot Run. This increase in quality is a direct reflection of process improvements generated during the course of the contract. Author
