Terry,
Take a look at this ceramic adhesive:
http://www.cotronics.com/vo/cotr/ca_electricallyresistant.htm
The following information is from the page the above link takes you to:
>28000F Resbond 919 Electrically Resistant
>
>Exceptionally high electrical resistance. Dielectric
>strength is 270 volts/mil and volume resistivity is 1011 ohm-cm (at room
>temp.).
>
>Maintains its high electrical resistance and dielectric strength at high
>temperature.
>
>Resbond 919 is ideal for: potting, sealing, coating cable end seals,
>igniters, heating coils, instrumentation, thermocouples, electronics, and
>many other electrical applications.
