| 46 Series glass/ceramic composite material. |
| The 46 is a structurally homogenous material which combines the wettability of electronic glasses with the strength of ceramics. The 46 replaces alumina and other glass/ceramics requiring batch furnace processing and reduces furnace time by 80%. With 46, metallizing and brazing steps are eliminated. The 46 produces high strength seals that can withstand temperatures up to 700°C. Sealed glass-ceramic headers can be post brazed up to temperatures of 1400°F without affecting hermeticity. The 46 has variable coefficient of thermal expansion from 110 to 220 (×10-7 in/in/°C). |
