Membrane Anneal Study: W510X, W600 Testing
I recently tested W510X and W600 described by Dave here for air permeability, rhodamine diffusion, and burst pressure. No air permeability was observed; even a sample with one very small pinhole (W600 800C anneal) only had a permeability of 11 cc/atm*cm2*s. To verify the lack of pores I performed rhodamine diffusion on the W600 700C…
