I was lookin over specs on the elan technology website, http://www.elantechnology.com and i saw this info, though that a few people around here might dig it. (this is the company that makes borostix)
46 Series glass/ceramic composite material.
After twelve months of successful field tests, Elan Technology, Inc. is introducing the 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).
The benefits of 46:
* Eliminates manufacturing steps.
* Reduces sealing time.
* Can match a wide range of metals.
* Can be easily machined.
* Has improved high temperature electrical properties.
* Has improved chemical durability.
