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.

they make borostix. the borostix evolved because they made resistors for tv tubes and monotor tubes. there are some of these tubes you can find at thrift stores and junk yards and use the resistor with boro. They specalize in fusing glass with metal. I also think its interesting that they have such a hi COE that varies so much. I've seen COE's varry, but not by 110. I'm into mixing metal and glass, and this looks like some fun to play with.
