| Along with ruthenium, rhodium, osmium, iridium, and platinum, it belongs to the platinum group of metals. |
| It has been further discovered that photosynthetic membranes can be transformed with metals other than platinum such as osmium and ruthenium. |
| Step on the throttle and the mixture is pumped past a catalyst made of ruthenium. |
| The ruthenium-bearing distillate is then treated with reducing agents to precipitate the ruthenium as a fine metal powder. |
| When ingested, ruthenium is retained in the bones making it highly toxic and carcinogenic. |
| The residue from rhodium sulfate leaching is fused with alkali nitrate salts to convert ruthenium to soluble sodium ruthenate. |
