1317-37-9 FeS Iron (II) Sulphide

Do you try the pyrite single mineral? It can be purchased from somewhere like Geo Discovery. Or, if you are looking for extremely pure pyrite, it may cost time to make. Just a thought.

I’m analyzing the electrochemistry of natural pyrite so I would be using synthetic as a control among other experiments. Thank you for the response.

Synthetic Iron Sulfide can be Pyrrotite. There is a patent on the internet describing the synthesis of pyrite.

As a control for your core research, I second with concern that you be sure you obtain a synthetic pyrite, as troilite or pyrrhotite or something else in the monosulfide range will not work as a control -p wrong stoichiometry, wrong crystal structure.

I doubt you want to get into the production of your own synthetic pyrite, and you need to stay on-side with a patent in any case. But you could look up the patent by (googling :synthetic pyrite" will return it very close to the top), contact that patent holder, explain your student status and what you want to do, and see if (s)he will send or sell you enough for your work. Only takes a few minutes to get the information and another 5 for an e-mail, and it might actually work in your circumstances. Maybe you and your professor consider exchanging any characterization data on the synthetic back with the owner, promise to acknowledge the assistance (of course), promise to send a copy of your dissertation - various good-faith, but cheap matters.

Thank you for the responses. I will contact the patent holder, good idea. I agree that monosulfide's won’t work. I've also seen suppliers providing Iron(II) disulfide as a powder(?) but I'm unsure if that would resemble the same properties, i assume not. Thanks again for the help.

Agreed with you about staying with patent for making a synthetic pyrite as control. This will ensure no question to be asked about whether the way of making pyrite is correct.

NIST also has a pyrite standard for use as a control in bioleaching.
