  2. Rhodium - Wikipedia

    en.wikipedia.org/wiki/Rhodium

    Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. [25] Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. [26] Rhodium has both a higher melting point and lower density than platinum.

  3. Magnetic implant - Wikipedia

    en.wikipedia.org/wiki/Magnetic_implant

    Perhaps the most important consideration is a coating for the magnet, as typical neodymium disk magnets are not suitable for implantation. Magnets must be coated in an inert and biosafe material, so the body does not attack the magnet. Popular magnet coatings include implant grade silicone, parylene, titanium nitride, gold and rhodium. Disc ...

    A large fraction of the chemical elements that occur naturally on the Earth's surface are essential to the structure and metabolism of living things. Four of these elements (hydrogen, carbon, nitrogen, and oxygen) are essential to every living thing and collectively make up 99% of the mass of protoplasm. [1]

  6. Synthesis of precious metals - Wikipedia

    en.wikipedia.org/wiki/Synthesis_of_precious_metals

    If the rhodium metal was then left for 20 years after fission, the 13.3 grams of rhodium metal would contain 1.3 kBq of 102 Rh and 500 kBq of 102m Rh. Rhodium has the highest price of these precious metals ($440,000/kg in 2022 [ 3 ] ), but the cost of the separation of the rhodium from the other metals needs to be considered [ editorializing ...

  7. Organorhodium chemistry - Wikipedia

    en.wikipedia.org/wiki/Organorhodium_chemistry

    Organorhodium chemistry is the chemistry of organometallic compounds containing a rhodium-carbon chemical bond, and the study of rhodium and rhodium compounds as catalysts in organic reactions. [ 1 ] Stable organorhodium compounds and transient organorhodium intermediates are used as catalyst such as in olefin hydroformylation , olefin ...

  9. Rhodium hexafluoride - Wikipedia

    en.wikipedia.org/wiki/Rhodium_hexafluoride

    Rhodium hexafluoride, also rhodium(VI) fluoride, (RhF 6) is the inorganic compound of rhodium and fluorine. A black volatile solid, [ 1 ] it is a highly reactive material which starts to slowly thermally decompose already at room temperature and a rare example of a rhodium(VI) compound.
