I am stuck on my design project until I find out the internal pressure of 4cc of Hexafluorobenzene inside a small ampoule at 250C. I am willing to pay for someone to work with me on that and other tracer materials.
Thanks so much for the comments, you guys are great. Adding a vapour space would solve the problem but this is getting more complicated than I had first thought. It's obvious I will need to get someone to provide consulting for this. Thanks so much for your insights.

Thanks, but to put it in real terms, we have 4cc Hexafluorobenzene contained in a sealed 4cc container operating at 90-100C but must be rated for short duration at 280C maximum. What would be the pressure @ 280C? Our problem is that there is a foil sealed opening in the container (for piercing...
The inside of large substation transformers is an environment of great liability. Nothing goes in that can stay there for 30 years or longer. The only joining methods used in these areas are silver brazing and welding, and that's the reason for having to weld the foil. Thanks

We are in the process of developing Tracer indicators. The concept includes a trace material, hexafluorobenzene. contained in a canister and released when conditions within the equipment warrent. The canister is approximately 5cc in volume and has a foil sealed opening. I am considering using...
Don't worry, I've been doing this 30 years so I've picked up a few things. I knew what I wanted but didn't want to spend the money to develop and establish parameters. I'm well versed in all aspects of joining but not welding .0005 foil to substrate. My first assumption was that it had to be...
Metman, dgallup; Thanks to you both and you are both correcto. I have discovered an old patent that shows how to manufacture a foil sealed opening using.....wait for it.....EB welding. Thanks, you were both on the right track. Thanks for your help and excellent responses.

Hello,
I have a very challenging welding problem and need help. Following are the issues and parameters.
We have a device that has two small chambers, each of which contains pressurized (15 psi)very low viscosity fluid (solvent).
The concept includes the mixing of two liquids to form a...
I'm not sure I understood your circumstances. Do you mean you already have them built? Well, the good news is that it's pretty obvious what your choices are. If your weld contours are good and not a lot of crevises or overlap, etc., you can use magnetic particle. Ultrasonics are out due to...
