Supplier of unusual inorganic from Poland

Boffis - 31-10-2021 at 02:29

Over the years a supplier of unusual inorganic compounds has been referred to on this forum but now I cannot find the name. The name is, as far as I recall, something like "Oxymet" but I have tried searching for this with the search engine and I have tried various similar name but I can't find a single reference.

Can someone please enlighten me as to the correct name? I believe the business is in Poland.

And they provide great service, worldwide!

Very many thanks! Onyxmet… God my memory is going gaga.

Yes, I can wholeheartedly recommend Onyxmet. The owner of the company is very helpful and the quality of the products is good! I purchased rare and difficult to obtain chemicals from them quite a few times.

I also recommend Onyxmet. Good experience with that helpful guy.

As for Onyxmet, it often does not indicate the purity of the chemicals, while others are suspiciously often 99.9% pure. I had a lot of elements and chemicals brought in from Onyxmet, and sometimes the quality was very poor, and it was clear from a simple glance that there wasn't the stated purity of 99.9%! If I really care about cleanliness I prefer Chemcraft, even if it's outside the European Union and the purchase gets very expensive because of custom and the like...It's nothing personal at all against Mr Thomas, I'm sure he tries and he cares about quality too, but he doesn't always keep it safe and probably doesn't have expensive equipment to check for purity. The problem is probably his suppliers, not him...

I think that all good suppliers every now and then make mistakes or have less than ideal purity of their products. Overall, I am happy with Onyxmet's products, but I am equally happy with Chemcrafts' products. With both of these suppliers I indeed had a disappointment once, but that was only once:
- Onyxmet had MnCl2.2H2O, a beautiful bright pink solid (much brighter than the more common MnCl2.4H2O). But when I received it, it appeared to be adultered with and a pink dye was added. I mentioned this to Tom and he made his excuse and investigated his supplier.
- Chemcraft sold V2O4, a quite uncommon oxide of vanadium (normally you can buy V2O5). V2O4 is a dark blue, nearly black solid and I now how some from another supplier. Chemcraft's material was dark green with a brownish hint. While experimenting with it I found out that the material contained a lot of vanadium in +5 oxidation state and I think that it is some indeterminate mix of V2O4 and V2O5.

I purchased mainly display samples from Onyxmet (e.g. elemental As, 3N and 5N in old containers with original labels, many binary compounds). From Chemcraft I purchased some display samples, but mostly chemicals for experimenting.

Thank you Wilco for conveying your experience! I know an expert in synthesizing extra-pure inorganic compounds. He made them all his life and exported them through a company he co-owned around the world, His wife died recently and he dropped everything, he's an older man now. He still has his supplies. I also got some VO2 and V2O3 from him, and it's exactly the color it should be according to literary data! He also offers elements and compounds spectroscopically pure! He probably doesn't speak much English because he studied and worked during the Soviet occupation of our country and everyone had to know Russian compulsively, English could only be taught privately because unfortunately it was considered the language of an imperialist enemy...If you're interested, write me an email and I'll tell you the details and send you a link...

So I just tried to place an order with Onyxmet. Can I ask those that have used them, are you supposed to pay based on the first confirmation email you get, or will they send another? If it is the first email, how do you make payment? Thanks in advance.

Every time I have ordered I have ended up having an email conversation with Tom to organise payment.

One time there was an option to make a direct deposit into an aussie bank account.

Ah good one, thanks for that.
