I get ours from Linde in Pennsylvania. $7.50/gram and it ships from Pelchem in South Africa. Took about 2 weeks to get here. The bottle the XeF2 was in was $280 and the air freight was $1800.

Hi,
~$100/gm through Sigma-Aldrich and $50/gm from Alfa Aesar.
I buy it from Pelchem (South Africa) ~1,000/200gms and ~$1,000 for Hazardous shipping (and it has a higher purity)
Regards,
Bob

I see that xenon difluoride can be purchased from Alfa Aesar. Has anyone consulted with the chemical supplier, their chemistry departments, or environmental health and safety to develop a protocol for reloading the canister with the crystals?
Best Regards,

The material is only available from Pellchem in South Africa, we got the past bottle through Middlesex Gas (Draper supplier of gases).

Dear colleagues,
Just recently, my custom made Xenon Difluoride etcher has become popular with many of my users and I found myself in the horrible and embarrassing predicament of running out of etchant. Since this is somewhat of a specialty item, lead times are astronomical. Is there anybody out there that can lend me a sample cylinder? I will replace it with an identical new one. The cylinder is aluminum and is 2” diameter by 10.5” long measured from the bottom to the centerline of the male VCR fitting on the valve. Similar or not so similar cylinders can be fitted, it’s just a matter of finding one.
Thank you in advance.
