Teflon would work. Just be careful around liquid oxygen, high 
pressures, zero gravity, and underrated heaters with broken 
thermostats. Especially while you're on the way to the moon.

Another method is to use a large incandescent, preferably infrared 
lamp positioned over the tank. Of course, clear liquids don't absorb 
as well as dark ones (like FeCl). I suppose you could put the tank in 
a microwave on low or defrost.  8-O
