After a high temperature electrical insulation
Plasma, Mon Feb 06 2017, 07:15AMHi for a project I'm working on I would like some material the would be a pipe, that can withstand flame temperature for about 2 seconds, and is a electrical insulator.
I plan to burn some gas in the pipe and have it travel through to the other end.
Hoping someone has a idea what I could use.

almost any engineering material will withstand 2 seconds of flame,
pressure/rupture considerations are probably more important,
can you give more details?

The coil will be about 0.5 meters diameter with about 10 turns.
Natural gas and compressed air will be mixed in a steel type chamber to hopefully achieve a flame front at 100m/sec around the tube, then vented into atmosphere.
I plan to have 10 spark gap spaced around the coil to discharge 9kv capacitor bank.
Side thing, was going to run a copper wire next to the tube to measure the voltage.

maybe ceramic, porcelain or glass. I dont think an organic material will survive what you describe. Even then cracking maybe an issue.

how about hose pipe ?
clear pvc tubing to see the flame ?

I like the idea of see through tube, even temporary, I should be able to see how far it travels.
Should be able to gauge if it will survive higher temperature at lower temperature and velocity during testing.

You need to know if the material you choose becomes a conductor when heated,
lest you make a Nernst Glower.
