Variables associated with the fabrication of metal-to-ceramic seals were investigated to understand the mechanisms of failures and to improve manufacturing processes. The program primarily involved an extensive reliability study in which ceramic bodies, metallizing mix tures, plating, sintering, brazing, and other sealing practices were statistically evaluated. Environmental, life, and leak path studies sup ported the primary investigations. Recommended manufacturing procedures and controls were in corporated into a manual on metal-to-ceramic sealing techniques. An operating nonpumping ion gage was constructed.
