Ceramics raw materials
A frequent remark here is that "it's available at a ceramics supplier". In the US, Laguna Clay is a major ceramics manufacturer and distributor. They have an extensive catalog, but of particular interest is their dry raw materials (PDF). It's worth a look through, as there are lot of metals as carbonates or oxides: lithium, strontium, antimony, vanadium,
neodymium, erbium (!) and all the common ones. They have calcium and sodium nitrate and phosphate (all four), silicon carbide, some fluorides, etc.
Make sure to ask for the prices on 50lb sacks, as the labor cost to down-package is often not worth it.
They have an extensive dealer/distributor network in the US and Canada. Raw material prices like these are dominated by shipping cost. The cheap way to do this is by
special order from a local retailer; they can just add your item to the freight truck that shows up periodically anyway.
I don't know who the big names are in Europe or elsewhere in the world. I'm sure there are people here who do, though.

Old time photography supply
Dont forget mining/assaying sites either.The also stock some worthwhile items/tech grade sodium nitrate,litharge etc etc .Ya really have to peruse a
sight.I havent checked with old time photographers supplys shops but odds are ther are still some hard core photoghraphers that love thier 50-80yr old
camera hobbys.And my understanding is old style photography can be a goldmine of chemicals.

Yes, a newsletter of a prominent photographic supplies dealer does occaisionally mention an old process that requires cyanide. But I never see any
for sale. Perhaps you have to make a special request and you have to be a trusted customer - just guessing here.
The single most important condition for a successful synthesis is good mixing - Nicodem

Close friend used to do all sorts of professional electroplating
back in the eARLY 60S-70'S.from hardcoating AL etc etc.He had access to more toxic chemicals and usefull acids,you name it.
Long term health AKA OSHA wasnt a prominent feature as a result his lungs sound like rocks in a tin can.The corrosive atmosphere and nonexistent
ventilation system ate his lungs in short order.The never used protective eyeware,or lab type resistant clothing or even basic respirators and his
lungs at 62 sound like it.
