-
- I'm sure they must have meant to say 760 times its own volume. The CRC
- HCP claims palladium can absorb 900 times its own volume at room temperture.
-
- As for density, the highest density element is Osmium at 22.6 g/cc, with
- gold at 19.3 g/cc and uranium at 19.07 g/cc.
-
- Palladium is 12 g/cc. 760 times 12 is 9120, or about 9 kg/cc, just like
- Tarl calculated. That is about 400 times more dense than Osmium. I doubt
- palladium expands 400 times its volume!
-
- By the way, for the curious, diamonds are only 3.5 g/cc.
