I have a 12 foot length of 14-gauge molybdenum wire that I have measured a resistance of 1.2 ohms. I would like to use it as a small heater coil.
How can I calculate the safe number of volts that I may give it without melting the wire?
Edit: I would like to operate this at a maximum of 1500C. Ideally it will be buried (protected) in refractory.
Edit 2: I read that molybdenum wire can be used as high temperature heating element, but I guess I just want to make sure that is indeed the case. I have variable voltage so I can start out low and raise it as needed.
NOTE: This is not the same low resistance MoSi2 heater elements I posted a question about yesterday - this is pure molybdenum 14 gauge wire.
