Sources of High temperature dielectric material

Sources of High temperature dielectric material

Sources of High temperature dielectric material

(OP)
Can anyone recommend a source/company that produces ultra high temperature dielectrics, 500 Celsius and above, for use in Microwave products. Prefer lower relative dielectric value ranges in the 3-6 range, but up to 10 may be OK too.
Size of the part required is approximately 10"x1"x0.060" max. and 2"x 0.5"x 0.030" minimum. Must be able to metallize the surface of the dielectric with some high temperature conductor.

Most commerical dielectrics are rated only up to 300 degrees Celsius.

I have looked at some products from Transtech in New Jersey. They make ceramic dielectrics of various dielectric values and temperature ranges. Are there any other sources for what I seek, options such as the tiles for the Space Shuttle, I'm curious what company manufactures those tiles.
Thanks
kch.

RE: Sources of High temperature dielectric material

There are many ceramic materials that would meet your needs. Quartz plate in particular has low dielectic and loss.
