Glass Melting and Sealing

PDF format (48 kb)

The Manufacturing Science & Technology Center performs process development of glass and glass-ceramic-to-metal seals. Small batches of specialty glass can be melted from reagent grade oxide powders. Glass and glass-ceramic-to-metal seals are made in microprocessor controlled inert atmospheres and are checked for hermeticity after sealing.

Sandia's extensive properties database of low melting solder glasses is used to aid in material and processing decisions when making glass-to-glass, ceramic-to-ceramic, and glass-to-ceramic seals. These seals are typically done in air at much lower temperatures than glass and glass-to-ceramic seals.
