Abstract : This report summarizes the work performed in the original Phase II Program and the results of the ARPA sponsored program. Prototypes of the Honey Comb Oxygen Generators (ARPA) as Solid State Oxygen Compressors for the J-T (Joule-Thomson) Cryocoolers were tested. Previous results conducted in the original Phase II Program contributed to this study, but are not totally documented. Rate Controlled Sintering Studies aided as a powerful diagnostic tool for the evaluation of the prepared power. The small, simple J-T Refrigerator provided the cooling system. The results of the performance of the ceramic toughening methods and stress analysis will greatly aid in the design and building of the Ceramic Honeycombs for the J-T Cryocooler Prototype. It is concluded that the results of this Phase II Program will provide excellent technology for the advancement to the next level of study.
