3200 Degrees C!!!  That is HOT!  It is what the Layman would call "White
Hot".

The CRC Applied Engineering Science Handbook lists 16 "Common Refractory
Materials"  The only one that has not melted at 3200C is graphite and it is
heavily sublimating at 3590 C.  Of the metals, only Tungsten has not melted.
Rhenium melted at 3180 C.

Normally  optical techniques are used to measure these temperatures, such as
an optical pyrometer.

I am really curious....What are you trying?

                Hello,

                I am looking for a good packaging/packaging material voor
MEMS and IC, which
                is capable of high temperatures (up to 3200 degrees
celcius). Does someone
                know which material I can use, or a company who makes these
packages? And,
                does someone know a company who makes MEMS
temperature-sensors for these
                high temperatures.

                Thanks,

                Armanda T. Hogedoorn
