Micro heating element?
I am looking for a tiny heating element that can reach 1000°+, something on the order of 2-3mm wide and 5mm long. I want to put it the closed end of
a quartz tube to create a “hot finger” for growing metal crystals by vapor deposition. Anyone aware of such a thing, either off the shelf or
easily home made?
Thanks

The elements used and sold for 'vaping' may do the job.
They are a short coil of Kanthal wire

Buy a spool of Nichrome/Kanthal wire, you can make your own heating elements in any shape or size you want, and they can run at any temperature up to
about 1400°C. The size you want won't draw much current at all, you can get away with a really simple controller (Think; Potentiometer and power
supply).

Thanks. I'm surrounded by DIY vapers, so this will be easier than I thought.

Maybe a cigarette lighter from an old car? They have a perfectly shaped small circular coil of wire that can get up to red heat at least.

Maybe there is something of use here: elec heated tube
The single most important condition for a successful synthesis is good mixing - Nicodem

They sell little SiC heaters on eBay. SiC is continuously good for around 1500C.

Or as suggested, induction (perhaps with a graphite inductor in your quartz tube):

PS. The induction heater with graphite would be good to around 3000C, provided of course the tube is kept cool and filled with argon (not just any
inert atmosphere) or a vacuum.
