Purer than the same exact thing but for a quarter of the price. On small quantities of things like Ir, Ru, Os, it's not worth my hassle to sell for less. We keep all the ruthenium as ruthenate or potassium ruthenium chloride, so I'd have to make a small batch of ruthenium just for you or reduce a bottle of standard grade material.

If you want to buy a lot of it, then I'd be glad to quote you a market + spot price. On the cheap metals like Os and Ru, that's typically $20-50 over spot Matthey Rustenberg price but that's on 5 ounces or more.

Hört sich eher nach Pulver an, aber ich frag nochmal nach. Wollte ihr das alle für eure Elementesammlung oder was habt ihr gegen Pulver?

I wish you'd have contacted me end of January. I'm accumulating Ru again and all I have to sell are my salts. Now it is several months later and stocks are low. That's why the high price now, because I work on a batch basis. I can make beads of the metal but my ebeam melter is awaiting new diffusion pump. The iridium wire will be horribly expensive. It's a bastard to draw.

We get Ru and Ir as byproducts of Pt refining for the most part. Every thousand ounces of platinum scrap that we typically see will have about 30-40 oz Ir, 20-30 oz Ru, and the balance Rh, Au, Pd. So it's sold only very rarely and the residues are refined after ion exchange resins, wipes, gloves, etc are burned at the end of the year and after all of the insolubles from Pt digestion are put together. It doesn't make sense to go through all the motions on small quantities, especially not at less than $120 an ounce.

Suppose I spare you this 10 g of ruthenium for $45 and make but a pittance, could you promise me considerable business on Ru, Re, Rh, Ir, Pt, and Pd? Ru is a difficult metal to dispose of for me. Iridium, platinum, and palladium are not.

What incentive is there, besides me just keeping old, antiquated prices that I've already honored?
