Hi Mehmet,
As CTE of Pyrex and Si are almost the same, the best way is that you use Anodic
bonding instead of an epoxy interface which has different CTE.

Subject: [mems-talk] interfacing high temperature microchannels
Hi all,
I am trying to interface a Si-Pyrex microchannel device that is going
to be heated up to ~600C. Do you have any ideas on how to interface the
channels? Are there certain epoxies or connects because at 600 almost
everything that is plastic melts. I have tried a couple of epoxies but their
TEC don't match the glass and it cracks the Pyrex on top. If there is no way
to do it with Si channels, I am open to consider other materials for channel
substrate material.
Thank you for the help,
Mehmet Aykol
