I normally use Li OD or Sulfate. Sometimes I add Rb salts. (I make the OD's from the metal into the heavy water since buying LiOD is getting costly). (for the underwater "plasma" systems I often us sulfonic acid (not sulfonic not sulfuric). DennisDate: Tue, 14 May 2013 14:57:02 -0400 Subject: Re: [Vo]:If I want to see it for myself...

Do you usually use a potassium salt? On Tue, May 14, 2013 at 2:50 PM, DJ Cravens <[email protected]> wrote: yes the silver alloy (anywhere from 20 to 25 % seems OK with 23% perhaps better). It doesn't seem to load as high but it doesn't "crack" near as much. Regular Pd will often crack as it gets very hard on loading. My personal preference is 5% Rh but the cost is prohibitive. The 10% Y is also good. The pure Pd (better than 4 nines) is very very temperamental. Another approach is to lightly coat your "rod" with Nafion to keep the surface impurities down during electrolysis which helps when your chemistry is a little sloppy (like mine often is). But you still need to not crack the Pd. Again load very slowly and preferably down around 10 C. I really hope you do start down the experimental path- we need more experimenters. If it is just going to be a few quick and dirty tries, you might want to look at co-deposit systems. Pd on Au on Cu is a reasonable place to start. (again, do your plating and loading cold before your do you runs). Some info is hard to find and is often over looked but the only real "secret" I know in this field is tenacity.

As noted hydrogen with silver. This is what JM recommended to Martin. It loads well without cracking. So they said and he confirmed. - Jed
