Iron Carbide standard
« on: March 03, 2022, 09:57:46 AM »
Hello everyone,

We're currently searching for an iron carbide standard. I've found just a few webstores (American Elements, Stanford Advanced Materials), but if any of you have a tested source, or might be able to send us a sawed off bit of a rod, I'd really appreciate it.

I'll try to check back in weekly for any responses. EDIT: my email is dominique.duguay  @  canada.ca  (remove spaces).

Thanks!

Dom

I wanted to make a clever chemistry joke, but the best ones argon.

One minor suggestion for iron carbide: be sure to obtain a single (or poly) crystal material, because we have found that powder sintered materials may not be stoichiometric.

Hi Dominique,

Geller Microanalytical sells Fe3C at 99.9 wt% purity (https://gellermicro.com/standards/std-list_12-2021.pdf).  I don't know if it is coarsely crystalline or not, nor do I know how much they charge for it (could be expensive).

Brian

EDIT:  Now that I look more closely at the list from Geller, they describe the form of the material as "metal foil."  I'm not sure exactly what that means, as natural cohenite is brittle.
