Questions about an experiment to make carbon boride

[Warpspeed13]

Ok what kind of environment do I have to create for the reaction to take place? I'm turning an old propane tank into a reaction chamber and to achieve the temperatures required for reaction I will run a DC current through the material. Will filling the chamber with argon be sufficient or does it need to be a vacuum chamber? If so how much of a vacuum is necessary?

 

Disclaimer: Do not try to replicate any of the conditions I just described unless you have experience with high pressures and electricity. Failure to take certain precautions could result in death or permanent injury to you or others. Contrary to iron man having shrapnel in your chest isn't a good thing.
