Hello all,
I am conducting a experiment where I need to heat up argon. I understand from publicly available resource that Nichrome or Kanthal heating elements protect themself by producing a oxide layer on its surface by reacting with oxygen from air at high temperatures.
1. Is using Nichrome/Kanthal A1 at temperatures of about 1000 C safe for extended durations like 3000 hours?
2. Would heating the elements in air in-between 100 hour experiments increase the durability?
Kind Regards,
Atul

Atul,
I see no difficulty in using nichrome at those temperatures for that period.
(120 days!)
How will you be controlling the heater current?
