I need to use nitrogen gas in a kiln to make an inert environment, do we have any N2 gas at the space I could use?
Would Argon work? That would actually be inert as well.
Josh,
Any idea how much you need?
You are right, but I want to follow the research paper exactly to see if I get their results, could always experiment later.
I haven’t done the calculations but I don’t think it would be “much” I just need to keep a positive pressure in the kiln.
Is there a purity standard you need?
Nitrogen is cheap. I have 2 40 CF nitrogen I can loan.
that sounds fine, if i use too much ill pay you back buddy.
To underscore Tim’s point
I estimate I need 24L
24L = .85ft^3
for a 4hr process at 100mL/min
I’m not sure what fittings they have currently setup because it was for medical oxygen which I understand to be different than what is used for industry/welding/etc.
According to the guy at Metroplex they already sell N2 with a purity of 99.999% so im not worried about the purity.
Is the Kiln at the space? How well is it sealed? How hot is it going to get?
the kiln is at the space, same one Science use for YBCO project. The material will be inside the kiln inside a crucible that has a hole drilled into it, the N2 gas will be pumped into that.
Why nitrogen?
May I ask if this is for the superconductor project, a follow up to it, or for something else?
It is for something else the YBCO project needs Oxygen not Nitrogen. I think Josh said it was for a foam.
How is the YBCO project going? I had some thoughts on it several months back when reading your background material posted on the wiki.
They are going the pyrophoric route for more intimately mixed materials. I also have concerns that our starting materials may be contaminated as they are ceramics/technical grade. Been too busy to help with the project anymore.
I’m gonna venture a 95% certainty at this point that this is the problem. Your background reading states not to use ceramics grade materials.
